• 【High Purity Graphite Crucible】 With 99.9% high-purity graphite and ash content below 0.1%, our crucible is not easy to be doped with impurities during the smelting process and can be used to melting high-purity precious metals.
• 【Stable Properties】The surfaces 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. 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.
• 【High Quality Materials】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.
• 【Quality Craftsmanship】Using high-quality craftsmanship, our graphite furnace can be used up to a maximum temperature of 1800℃.Not easy to crack during high-temperature casting, long service life. Pour opening groove design makes it easy to use.
• 【Wide Application】Melt your precious, or non-precious metals and can handle large batches of material. melting and casting metals such as gold, silver, brass, aluminum, copper, zinc, plumbum, etc.
