细陶瓷(高级陶瓷、高级工业陶瓷).非氧化块体陶瓷的抗氧化性测定

[中文适用范围]： 本国际标准描述了测定氮化硅、赛隆和碳化硅等非氧化物整体陶瓷在高温下抗氧化性的试验方法。 本国际标准旨在评估试件在氧化气氛中高温氧化后的质量和尺寸变化，并评估氧化是否对随后的强度产生显着影响。 该测试方法可用于材料开发、质量控制、表征和设计数据生成目的。 注：1) 有时写作 SiAION 是含有硅、铝、氧和氮的陶瓷的缩写。 [外文原描述]： ISO 20509:2003 describes the method of test for determining the oxidation resistance of non-oxide monolithic ceramics, such as silicon nitride, sialon and silicon carbide at high temperatures. This International Standard is designed to provide an assessment of the mass and dimensional changes of test pieces following oxidation at high temperature in an oxidizing atmosphere, and to assess whether oxidation has a significant effect on the subsequent strength. This test method may be used for materials development, quality control, characterization, and design data generation purposes.
