refer to inorganic, non-metallic solids, in which inorganic compounds are the main constituents. It is not a single class but has further branches. Different ceramics differ much from each other in their choice of raw material, processes of preparation, characteristics in performance, and uses. They form the entire system of ceramic materials. A more detailed introduction will follow.<\/p>\n<h2 id=\"Basic-Properties-of-Ceramic-Materials\"><span class=\"ez-toc-section\" id=\"Basic_Properties_of_Ceramic_Materials\"><\/span><strong><b>Basic Properties of Ceramic Materials<\/b><\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The excellent properties of ceramic materials make them irreplaceable in many fields.<\/p>\n<h3 id=\"Mechanical-Properties\"><span class=\"ez-toc-section\" id=\"Mechanical_Properties\"><\/span><strong><b>Mechanical Properties<\/b><\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Ceramics possess excellent hardness, much superior to metals. They also show a high level of strength with great stiffness and resistance to deformation. The fracture toughness of ceramics like zirconia and silicon nitride is quite good, along with excellent impact resistance. In addition, compared with metals, ceramics are much more wear-resistant, providing great advantages in wear-prone conditions.<\/p>\n<h3 id=\"Physical-Properties\"><span class=\"ez-toc-section\" id=\"Physical_Properties\"><\/span><strong><b>Physical Properties<\/b><\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Ceramics have excellent high-temperature resistance. With low coefficients of thermal expansion, their size changes with temperature increases or decreases are minimal, and they display excellent thermal stability. Ceramics will not crack upon rapid temperature change due to their high thermal shock resistance. In addition, most ceramics have a lower density than metals, lighter and more efficient in reducing equipment load. They\u00a0are non-magnetic and not affected by magnetic fields. Some ceramics have good biocompatibility for implantation in the human body.<\/p>\n<h3 id=\"Chemical-Properties\"><span class=\"ez-toc-section\" id=\"Chemical_Properties\"><\/span><strong><b>Chemical Properties<\/b><\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Ceramics possess a very high corrosion resistance.

Under extreme conditions such as high temperatures, strong corrosion, high wear and excellent insulation, both metals and plastics show conspicuous deficiencies. The demands can be met by ceramics, which fill the performance gap.<\/p>\n<p>In terms of <strong><b>mechanical properties<\/b><\/strong>, ceramics are much harder and enjoy better wear resistance compared to metals and plastics. Metals have a medium hardness and general wear resistance, while plastics are soft and tend to wear easily. The wear resistance of ceramics is tens or even hundreds of times that of metals, offering better performance in cases of high abrasion.<\/p>\n<p>In <strong><b>thermal properties<\/b><\/strong>, ceramics exhibit outstanding resistance to high temperatures, which neither metals nor plastics can provide. Metals soften and oxidize at high temperatures. Plastics have weak heat resistance, softening above 200\u2103. Ceramics do not lose shape or strength at temperatures exceeding thousands of degrees centigrade. Several may even resist an extreme temperature of up to 3000\u2103. In addition, its coefficient of thermal expansion is low with great thermal stability. It does not crack due to the sudden temperature change.<\/p>\n<p>According to <strong><b>chemical properties<\/b><\/strong>, ceramics are highly resistant to corrosion, oxidation and super chemical stability. They will not deteriorate in strong acids, alkalis or harsh environments. Ceramics will neither rust nor age. But metals will deteriorate when exposed to acid and alkali corrosion. Plastics tend to age under UV light, ozone, and other environmental factors. Their lifespan is generally shorter. In comparison, ceramics keep performance stable even in complex environments.<\/p>\n<p>The <strong><b>electrical properties<\/b><\/strong>\u00a0make ceramics irreplaceable as insulators in high-temperature and high-frequency fields. The volume resistivity is high, with good dielectric strength. All metals are conductive and fail to meet the insulation requirements. Plastics, though insulators, will fail in high-temperature environments. Ceramics can well match the requirements of such high-power electronic devices.<\/p>\n<p>Besides these special properties, ceramics offer advantages in general performance as well. Being less dense than metals, ceramics provide lighter equipment. Most ceramics are non-magnetic, which makes them suitable for use in special environments where magnetic interference must be avoided, such as in MRI machines. Those advantages further extend the application range of ceramics.<\/p>\n<h2 id=\"Common-Questions\"><span class=\"ez-toc-section\" id=\"Common_Questions\"><\/span><strong><b>Common<\/b><\/strong><strong><b>\u00a0Questions<\/b><\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3 id=\"What-is-the-difference-between-ceramics-and-pottery\"><span class=\"ez-toc-section\" id=\"a_What_is_the_difference_between_ceramics_and_pottery\"><\/span><b><\/b><strong><b>a) What is the difference between ceramics and pottery?<\/b><\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Ceramics is a broad term that encompasses both traditional ceramics and advanced ceramics.

The latter includes not only traditional products like pottery, but also advanced ceramics with superior performance.<\/p>\n<h3 id=\"How-are-ceramics-made\"><span class=\"ez-toc-section\" id=\"b_How_are_ceramics_made\"><\/span><b><\/b><strong><b>b) How are ceramics made?<\/b><\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The basic manufacturing process of ceramics includes the preparation of raw materials, forming, sintering, and post-processing.<\/p>\n<figure id=\"attachment_20801\" aria-describedby=\"caption-attachment-20801\" style=\"width: 622px\" class=\"wp-caption alignnone\"><img decoding=\"async\" class=\"size-full wp-image-20801 lazyload\" src=\"data:image\/gif;base64,R0lGODlhAQABAIAAAAAAAP\/\/\/yH5BAEAAAAALAAAAAABAAEAAAIBRAA7\" data-src=\"https:\/\/nkmceramic.com\/wp-content\/uploads\/2025\/11\/7-Advanced-Ceramics-Manufacturing-Process.jpg\" alt=\"Advanced Ceramics Manufacturing Process\" width=\"622\" height=\"425\" \/><figcaption id=\"caption-attachment-20801\" class=\"wp-caption-text\"><noscript><img decoding=\"async\" class=\"size-full wp-image-20801 lazyload\" src=\"https:\/\/nkmceramic.com\/wp-content\/uploads\/2025\/11\/7-Advanced-Ceramics-Manufacturing-Process.jpg\" alt=\"Advanced Ceramics Manufacturing Process\" width=\"622\" height=\"425\" \/><\/noscript> Advanced Ceramics Manufacturing Process<\/figcaption><\/figure>\n<p>During the raw material preparation, a selection of natural minerals or high-purity synthetic powders is made according to the intended application.<\/p>\n<p>Depending on the form and the precision needed, the forming involves traditional methods of throwing, slip casting, and pressing, or precision techniques such as dry pressing, isostatic pressing, and injection molding.<\/p>\n<p>Sintering is the most important step. The ceramics must be heated to a specific temperature and in an appropriate atmosphere so that the particles may bond and can become densely compacted.<\/p>\n<p>After sintering, some of the products are ready to ship after visual inspection. For those products that require high precision, other processes such as cutting, grinding, and polishing are performed. Performance testing is done to ensure the ceramic will meet quality standards.<\/p>\n<p>Ceramic materials, with excellent performance, have become irreplaceable key materials that metals and plastic cannot substitute. Traditional ceramics meeting the needs of daily life and basic construction. Advanced ceramics supporting the development of high-tech fields. Ceramics are now important materials both in modern industry and everyday life. As materials science continues to develop, the performance of ceramics will always be optimized, and application scenarios will increasingly broaden, offering new momentum to industrial upgrading and technological development.<\/p>\n<p>If you are looking for a reliable advanced ceramics supplier, please reach out to <a href=\"https:\/\/nkmceramic.com\/\"><u>Newthink New Materials<\/u><\/a>.
