Graphite crucibles are heat resistant containers that store materials and samples for various high temperature applications. 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 crucibles have many applications within the foundry, laboratory testing, jewelry making and fusion industries. Crucibles are thick, cup-like containers that come in many different shapes and sizes, with or without a removable lid and spout, which eases the pouring process. They may be barrel, cylinder or conical shaped, wide-form with a shallow, low profile, or high-form, with high, tapered walls. The graphite may be regular or high purity, and usually contains a high percentage of graphite, which is often mixed with clay. Crucibles of any size or material are measured in milliliters. Fine Features of Graphite crucible 1) High purity 2) Fine grain 3) Good performance of electrical conductivity and thermal conductivity 4)High density 5)Good corrosion resistance 6)Resists thermal shock, oxidation and abrasions well 7) High mechanical strength 8) Low permeability
