Silicon carbide bricks, insensitive to the angle of abrasive attack, enjoy stable wear resistance under conditions like high-speed scouring and particle impact.<\/p>\n<p>Besides, they have excellent resistance to corrosion, with the exception of hydrofluoric acid, and are resistant to corrosion by all forms of corrosive media. Moreover, their resistance to bending is more than 20 MPa, allowing them to bear high-load impacts without distorting. Hence, silicon carbide bricks find wide applications under extreme conditions-for example, blast furnace linings in steel industries and pipelines in mineral processing plants.<\/p>\n<figure id=\"attachment_20938\" aria-describedby=\"caption-attachment-20938\" style=\"width: 1280px\" class=\"wp-caption alignnone\"><img decoding=\"async\" class=\"size-full wp-image-20938 lazyload\" src=\"data:image\/gif;base64,R0lGODlhAQABAIAAAAAAAP\/\/\/yH5BAEAAAAALAAAAAABAAEAAAIBRAA7\" data-src=\"https:\/\/nkmceramic.com\/wp-content\/uploads\/2025\/11\/6-Application-of-Wear-Resistant-Silicon-Carbide-Bricks-1.jpg\" alt=\"Application of Wear-Resistant Silicon Carbide Bricks\" width=\"1280\" height=\"720\" \/><figcaption id=\"caption-attachment-20938\" class=\"wp-caption-text\"><noscript><img decoding=\"async\" class=\"size-full wp-image-20938 lazyload\" src=\"https:\/\/nkmceramic.com\/wp-content\/uploads\/2025\/11\/6-Application-of-Wear-Resistant-Silicon-Carbide-Bricks-1.jpg\" alt=\"Application of Wear-Resistant Silicon Carbide Bricks\" width=\"1280\" height=\"720\" \/><\/noscript> Application of Wear-Resistant Silicon Carbide Bricks<\/figcaption><\/figure>\n<h3><span class=\"ez-toc-section\" id=\"Military\"><\/span><strong><b id=\"military\">Military<\/b><\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>In personal protective gear and armored vehicle defense, <a href=\"https:\/\/nkmceramic.com\/silicon-carbide-plates\/\"><u>silicon carbide bulletproof plates<\/u><\/a>\u00a0have become essential materials for military protection\u00a0for\u00a0their core advantages of strong protection and lightweight. As the core layer of bulletproof vests, it uses two mechanisms to resist projectile impact.<\/p>\n<p>Through the combination of high hardness and high strength, the bullethead is quickly blunted upon impact, while the impact energy is dispersed across the entire plate, absorbing the shock efficiently. The lightweight feature is also significant. With\u00a0the same level of protection, silicon carbide bulletproof plates are about 20% lighter than alumina plates,\u00a0improving operational mobility. Additionally, silicon carbide bulletproof plates are more cost-effective. They\u00a0provide 80%-90% of the protection capability of the top-tier bulletproof material, boron carbide, but at a much lower cost. Therefore, silicon carbide is widely used in military equipment such as armored vehicles, bulletproof vehicles and vests.<\/p>\n<figure id=\"attachment_20939\" aria-describedby=\"caption-attachment-20939\" style=\"width: 1280px\" class=\"wp-caption alignnone\"><img decoding=\"async\" class=\"size-full wp-image-20939 lazyload\" src=\"data:image\/gif;base64,R0lGODlhAQABAIAAAAAAAP\/\/\/yH5BAEAAAAALAAAAAABAAEAAAIBRAA7\" data-src=\"https:\/\/nkmceramic.com\/wp-content\/uploads\/2025\/11\/7-Impact-Absorbing-Silicon-Carbide-Bulletproof-Plates-1-scaled.jpg\" alt=\"Impact-Absorbing Silicon Carbide Bulletproof Plates\" width=\"1280\" height=\"720\" \/><figcaption id=\"caption-attachment-20939\" class=\"wp-caption-text\"><noscript><img decoding=\"async\" class=\"size-full wp-image-20939 lazyload\" src=\"https:\/\/nkmceramic.com\/wp-content\/uploads\/2025\/11\/7-Impact-Absorbing-Silicon-Carbide-Bulletproof-Plates-1-scaled.jpg\" alt=\"Impact-Absorbing Silicon Carbide Bulletproof Plates\" width=\"1280\" height=\"720\" srcset=\"https:\/\/nkmceramic.com\/wp-content\/uploads\/2025\/11\/7-Impact-Absorbing-Silicon-Carbide-Bulletproof-Plates-1-scaled.jpg 2560w, https:\/\/nkmceramic.com\/wp-content\/uploads\/2025\/11\/7-Impact-Absorbing-Silicon-Carbide-Bulletproof-Plates-1-768x433.jpg 768w, https:\/\/nkmceramic.com\/wp-content\/uploads\/2025\/11\/7-Impact-Absorbing-Silicon-Carbide-Bulletproof-Plates-1-1536x865.jpg 1536w, https:\/\/nkmceramic.com\/wp-content\/uploads\/2025\/11\/7-Impact-Absorbing-Silicon-Carbide-Bulletproof-Plates-1-2048x1154.jpg 2048w\" sizes=\"(max-width: 1280px) 100vw, 1280px\" \/><\/noscript> Impact-Absorbing Silicon Carbide Bulletproof Plates<\/figcaption><\/figure>\n<h3><span class=\"ez-toc-section\" id=\"Mechanical_Sealing\"><\/span><strong><b id=\"mechanical-sealing\">Mechanical Sealing<\/b><\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><a href=\"https:\/\/nkmceramic.com\/silicon-carbide-seal-ring\/\"><u>Mechanical seals<\/u><\/a>\u00a0require components that are highly resistant to corrosion, wear, and high temperature. Silicon carbide ceramics boast corrosion and wear resistance, high thermal conductivity and low density that are the keys in different products.<\/p>\n<p>Silicon carbide is widely used to manufacture mechanical seals such as seal rings and shaft sleeves. These ceramic seals perform much better under extreme conditions of pressure, speed, and corrosion than their metal counterparts and last longer. These are applied in industries such as the petrochemical industry and the pump valve industry. Silicon carbide bearings are preferred in high-speed applications or when strong acids or alkalis exist, showing better wear resistance compared to metal bearings and higher operating temperatures (up to 1600\u00b0C) than zirconia. Because of this, silicon carbide ceramics have been adopted in place of conventional materials, solving the problem of short-lived seals against their lifetimes in demanding sectors.<\/p>\n<figure id=\"attachment_20940\" aria-describedby=\"caption-attachment-20940\" style=\"width: 1280px\" class=\"wp-caption alignnone\"><img decoding=\"async\" class=\"size-full wp-image-20940 lazyload\" src=\"data:image\/gif;base64,R0lGODlhAQABAIAAAAAAAP\/\/\/yH5BAEAAAAALAAAAAABAAEAAAIBRAA7\" data-src=\"https:\/\/nkmceramic.com\/wp-content\/uploads\/2025\/11\/8-Drawings-and-Product-of-Silicon-Carbide-Mechanical-Seal-1-scaled.jpg\" alt=\"Drawings and Product of Silicon Carbide Mechanical Seal\" width=\"1280\" height=\"720\" \/><figcaption id=\"caption-attachment-20940\" class=\"wp-caption-text\"><noscript><img decoding=\"async\" class=\"size-full wp-image-20940 lazyload\" src=\"https:\/\/nkmceramic.com\/wp-content\/uploads\/2025\/11\/8-Drawings-and-Product-of-Silicon-Carbide-Mechanical-Seal-1-scaled.jpg\" alt=\"Drawings and Product of Silicon Carbide Mechanical Seal\" width=\"1280\" height=\"720\" \/><\/noscript> Drawings and Product of Silicon Carbide Mechanical Seal<\/figcaption><\/figure>\n<h3><span class=\"ez-toc-section\" id=\"Other_Fields\"><\/span><strong><b id=\"other-fields\">Other Fields<\/b><\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Silicon carbide ceramics also play a critical role in several other industrial sectors.
