What is the difference between bending strength and tensile strength of ceramics?<\/b><\/strong><\/p>\nTensile strength resists pure stretching force. Bending strength resists comprehensive flexural stress with both tension and compression. Bending strength data is more relevant for most ceramic structural parts.<\/p>\n
Why do SiC ceramics have better high-temperature bending strength than ordinary ceramics?<\/b><\/strong><\/p>\nSiC has strong atomic bonding forces and a stable crystal structure. It does not soften or deform easily under high heat. It maintains stable flexural performance at ultra-high temperatures where ordinary ceramics fail.<\/p>\n
How to judge if ceramic bending strength meets production requirements?<\/b><\/strong><\/p>\nYou can refer to ASTM and ISO standard test data. Match the material strength index with your equipment\u2019s load and temperature working conditions. A reserved strength margin is necessary for long-term operation.<\/p>\n
Will repeated mechanical impact reduce ceramic’s bending strength?<\/b><\/strong><\/p>\nYes. Severe frequent impact may produce internal micro-cracks. However, high-quality sintered SiC ceramics have strong crack resistance. Their strength attenuation is far lower than other ceramic materials under normal cyclic loads.<\/p>\n
What bending strength value is suitable for industrial structural ceramics?<\/b><\/strong><\/p>\nGeneral industrial scenarios require above 300 MPa. High-temperature and high-load working conditions need 400 MPa or higher stable bending strength to ensure long-term safe operation.<\/p>\n
