Product Description
Product Overview
Silicon Carbide Graphite (SiC-Graphite) crucibles are advanced composite ceramics engineered specifically for high-temperature melting of precious metals including gold, silver, and platinum. These crucibles combine silicon carbide and graphite through isostatic pressing and high-temperature sintering processes, creating a superior material that overcomes the limitations of pure graphite or silicon carbide crucibles.
