标准摘要
[中文适用范围]： 此文档描述了使用布拉格-布瑞塔诺衍射仪确定氮化物和氧氮化物结合的碳化硅耐火制品中通常显现的矿物相的方法。它包括样品制备细节以及定性和定量分析矿物相组成的通用原则。α-Si3N4、β-Si3N4、Si2ON2、AlN 和 β’-SiAlON 的定量测定方法进行了描述。对于 α-Si3N4、β-Si3N4、Si2ON2、AlN 和 β’-SiAlON 的定量测定，基于样品的总氮含量的细化程序进行了描述。注意 样品总氮含量分析采用 ISO 21068-3 标准。 [外文原描述]： This document describes methods for the determination of mineralogical phases typically apparent in nitride and oxy-nitride bonded silicon carbide refractory products using a Bragg-Brentano diffractometer. It includes details of sample preparations and general principles for qualitative and quantitative analyses of mineralogical phase composition. Quantitative determination of α -Si 3 N 4 , β -Si 3 N 4 , Si 2 ON 2 , AlN, and β ’- SiAlON are described. For quantitative determination of α-Si 3 N 4 , β-Si 3 N 4 , Si 2 ON 2 , AlN and β’-SiAlON refinement procedures based on the total nitrogen content of the sample are described. NOTE ISO 21068-3 is used for the analysis of the total nitrogen content of the sample.
