●🔥【High Purity Graphite】 With 99.9% high-purity graphite and 1.8-1.82 g/cm³ high density, our crucible is not easy to be doped with impurities during the smelting process and can be used to melting high-purity precious metals. ●🔥【GROOVED GRAPHITE CRUCIBLE】Grooved graphite crucible made of natural graphite with good thermal conductivity and high temperature resistance, and has a small thermal expansion coefficient during high temperature use. Specially designed for easy removal from the furnace say no to any metal waste. ●🔥【Reliable Quality】Using high-quality craftsmanship, our graphite furnace can be used up to a maximum temperature of 1300℃.Not easy to crack during high-temperature casting, long service life. Pour opening groove design makes it easy to use. ●🔥【Stable Properties】The surface of the graphite crucible has a special glaze layer and dense molding material, which greatly improves the corrosion resistance of the product and extends its service life. Compared to clay graphite crucibles, our high-purity graphite crucibles can still maintain stability when exposed to strong acids and alkalis and are not prone to be corroded and oxidized. ●🔥【Wide Application】In metallurgy, foundry, machinery, chemical, and other industrial sectors, graphite crucibles are widely used in non-ferrous metal smelting, such as gold, silver, copper, aluminum, and lead.
