Crucibles

Graphite crucible has good thermal conductivity and high temperature resistance. Thermal expansion coefficient is small. It has a certain strain resistance to acid and alkaline solution of strong corrosion resistance and excellent chemical stability.It is widely used in metallurgy, casting, mechanical, chemical and other industries.

Graphite crucible are heat resistant containers that store materials and samples for various high temperature applications. Crucibles are thick, cup-like containers that come in many different shapes and sizes and are widely used in applications from industrial to chemical, commercial to residential. They can be fabricated with or without a removable lid and occasionally with a spout, which eases the pouring process.

Graphite crucible are  barrel, cylinder or conical shaped, wide-form with a shallow, low profile, or high-form, with high, tapered walls. Crucibles are made of metals like copper, platinum, quartz or porcelain, but graphite is a cost saving alternative to these more expensive materials. Graphite is a chemically inert, temperature resistant mineral that fares well in ovens and furnaces. It resists thermal shock, oxidation and abrasions well, and won’t melt, burn or chemically change in extreme conditions.

Graphite crucible temperatures as high as 5000°F and so can be used in furnaces and high heat processes. Graphite crucibles have many applications within the foundry, laboratory testing, jewelry making, plumbing fixtures, valves, sprinklers, and other heavy-duty products. They are further used in chemical analysis, store materials and samples during fusion and mixing processes, in ash content determination, to melt precious metals, and in foundries to melt many different metals.
