Fine ceramics (advanced ceramics, advanced technical ceramics). Silicon nitride materials for rolling bearing balls and rollers Ingestion-build-483481 Scope This document specifies the requirements for preprocessed silicon nitride materials for rolling bearing balls and rollers. This document provides a classification defining physical and mechanical properties of silicon nitride preprocessed bearing rolling element materials. The materials are classified in three categories by the specification of characteristics and microstructures. Methods for sample preparation and observation of

is also included

— requirements on design of equipment and selection of materials

commissioning and maintenance of gas-powered hot-water supply systems

may also be determined by this method
