T/NXCL 001-2021 Submicron silicon carbide micro powder for fine ceramics

Scope

Main technical content: This document specifies the definition, technical requirements, test methods, physical and chemical indicators, inspection rules, and packaging, marking, transportation, and storage of submicron silicon carbide powders for fine ceramics. It defines the scope and classification of submicron silicon carbide powders applicable to this standard. It also specifies the measurement methods and technical requirements of the referenced documents, as well as product inspection, sampling, packaging, and transportation. During the application process, customers will first check the particle size and particle distribution of the powder, as well as the purity of the powder and the content of major impurities. Under certain conditions, testing the specific surface area of the powder as a supplementary measure is more conducive to determining the quality of the powder, which is often required by foreign users. Due to the very fine particle size of submicron powders, the use of different instruments for testing can greatly affect the test results. Therefore, it is recommended to select testing instruments according to the customer's requirements and try to make them consistent with the customer's detection instruments to minimize differences.
