■ Introduction:
The fused silica ceramic melting bowl dish crucible is a specialized container used in high-temperature applications such as melting and casting metals, alloys, and other materials. The fused silica ceramic bowl is made of fused silica ceramic, a material known for its high thermal stability, resistance to thermal shock, and low thermal expansion. The fused silica melting dish is designed to withstand extreme temperatures, typically up to 1650°C, without cracking or breaking. The fused silica crucible dishes is commonly used in industries such as metallurgy, foundries, and research laboratories for a variety of applications, including casting, melting, refining, and analyzing materials.
