精细陶瓷（高级陶瓷 高级工业陶瓷） 陶瓷粉末自然烧结致密化性能的测定

[中文适用范围]： 本文件规定了在不施加任何外部压力或外部致密化力的情况下在高温下烧结由粒状或非粒状陶瓷粉末制成的陶瓷粉末压块的致密化程度的测试方法。 该测试方法适用于纯氧化物、氧化物和固溶体的混合物，也适用于可在真空或恒定气压（1巴或更低）下烧结以防止氧化或氧化的非氧化物（例如碳化物、氮化物）。 分解。 该测试方法不适用于只能使用压力辅助烧结技术（例如热压（HP）、热等静压（HIP）、气压烧结（GPS）或放电等离子烧结（SPS））进行烧结的陶瓷。 在有报道存在无机烧结添加剂的情况下，可以使用无机烧结添加剂。 [外文原描述]： This document specifies the test method to determine the extent to which ceramic powder compacts made of granulated or ungranulated ceramic powders are densified, when they are sintered at a high temperature without the application of any external pressure or external densification force. The test method is applicable to pure oxides, mixtures of oxides and solid solutions, and is also applicable to non-oxides (e.g. carbides, nitrides) that can be sintered under vacuum or constant gas pressure (1 bar or less) to prevent oxidation or decomposition. The test method is not applicable to ceramics that can only be sintered using pressure-assisted sintering techniques such as hot pressing (HP), hot isostatic pressing (HIP), gas pressure sintering (GPS) or spark plasma sintering (SPS). Inorganic sintering additives can be used where their presence is reported.
