What is Crucible?

The gold melting crucible is mainly made of crystalline natural graphite. Graphite crucible has good thermal conductivity and high temperature resistance. During high temperature use, the coefficient of thermal expansion is small, and it has certain strain resistance to rapid heat and rapid cooling. It has strong corrosion resistance to acid and alkaline solution and has excellent chemical stability. Because of its excellent performance, graphite crucible is widely used in the metallurgy, foundry, machinery, chemical and other industrial sectors for the smelting of alloy tool steel and the smelting of non-ferrous metals and their alloys.

Graphite crucible is a container applied to hold metal for smelting in a furnace. And it can withstand the extreme temperatures encountered in smelting metals. Hence the crucible material must have a much higher melting point than the melted metal and also it must have good strength even when white hot.

Furthermore, graphite crucible can withstand the high temperature, and has good resistance to chemical erosions and thermal shock.

The Application and Advantage of The Crucible

It is commonly used for precious metal such as gold melting, silver melting, platinum melting, etc. In addition, graphite crucible is also ideal for the melting of aluminum, copper, stainless steel and etc.

Graphite crucible should be stored in dry place and do not get it wet. After drying the crucible, don’t make it touch with water. Also be careful not to give a mechanical impact force, not from a fall or impact.

Crucibles are mainly used to smelt steel, iron and other non-ferrous metals such as copper, brass, zinc and lead and their alloys. It is available in a variety of sizes ranging from 250g to 10kg.

It is used to refine high-purity metals, as well as to be used to melt small amounts of precious metals such as gold, silver, platinum and high purity metals or high melting point metals and oxides.

The advantage of graphite crucible is that it has well corrosion resistance and impact resistance performance, so to ensure the reliability of product quality. It also has excellent resistance to strong acid and strong alkali, which guarantees it with a long service life. The component of material is under strict control. It ensures that graphite crucible will not pollute the metals when dissolving.
