A 3kg graphite crucible can hold 3kg of gold; other material quantities will vary. This 3kg custom graphite crucible is of reliable quality. 99.9% high purity, excellent thermal stability and performance, not easy to be corroded and oxidized, and grooves are easy to use. Gold, silver, copper, iron, aluminum and other non-ferrous metals can be melted in this graphite crucible.

Graphite crucibles are wearing parts and need to be replaced after prolonged use.

Features of graphite crucible 3kg

1. High-purity graphite, 99.9% high-purity graphite and 1.8-1.82 g/cm³ high density, our crucibles are not easy to be doped with impurities during the smelting process, and can be used to smelt high-purity precious metals.

2. Good thermal conductivity, this small graphite crucible has excellent thermal conductivity, which can greatly shorten the melting time and save energy.

3. Reliable quality, our graphite furnace adopts high-quality craftsmanship and can be used up to 1300℃. High temperature casting is not easy to crack and has a long service life. Inverted groove design, easy to use.

4. Stability, our high-purity graphite crucibles remain stable when exposed to strong acids and alkalis, and are not easy to corrode and oxidize.

5. Wide range of applications, in metallurgy, casting, machinery, chemical and other industrial sectors, graphite crucibles are widely used in gold, silver, copper, aluminum, lead and other non-ferrous metals smelting.

6. The grooved graphite crucible is a grooved graphite crucible made of natural graphite, which has good high temperature resistance and small thermal expansion coefficient when used at high temperature. Designed for easy removal from furnaces, say no to any metal scrap.

7. Large capacity, 3KG/334ML capacity, can melt 6.4KG gold, 3.5KG silver, 3KG copper, 0.9KG aluminum. The operating temperature is less than or equal to 1800°C, and it can smelt gold, silver, platinum and other alloys, as well as other precious metals, smelt and cast metals.
