Silicon carbide crucibles are used by jewelry makers and metal craftspeople alike to melt gold, silver, and platinum into jewelry and metal objects. Highly durable, they can withstand high temperatures without deforming or cracking under pressure. Before using new crucibles, they should be heated slowly so as to allow any moisture that has built up inside to evaporate. High Temperature Resistance Silicon carbide crucibles can withstand high temperatures, making them an excellent choice for melting metals. Furthermore, they’re resistant to thermal shock and corrosion; graphite crucibles tend to oxidize at higher temperatures while silicon carbide features a protective coating against this. They can be found in fuel fired furnaces, electric …
