Clay bonded Graphite Crucibles are made from high purity and fine grain graphtie.the binder is the clay and the main materials is crystalline flake graphite. It can be used in non-ferrous metals smelting , carbide feed generator carburization quenching.
The clay bonded graphite crucibles have the characteristics such as high temperature resistant, quickly heat conduction, good thermal shock resistance, good thermal stability,good corrosion resistance.
We have two kind of the clay graphite crucibles: the first kind can be in high temperature degree of fire resistance 1650°C, volume density1.65g/cm3,the second kind graphite crucible at degree of fire resistance 1400°C, its volume density1.52g/cm3.
The clay bonded graphite crucible with good thermal conductivity and high temperature resistance, at high temperature in use process, small thermal expansion coefficient, the thermal shock, quenching has certain strain resistance. Of acid and alkaline solution of strong corrosion resistance, excellent chemical stability.
The clay graphite crucibles are used in metallurgy, casting, machinery, chemical and other industries, because it has more excellent performance, so it also has been widely used in alloy tool steel smelting and smelting of nonferrous metals and their alloys. And has a good technical and economic effect.
Our clay graphite crucibles are of good quality, long service time, also we can customize any size as per your requirement. It has top quality crucibles offer consistent performance when melting ferrous, onferrous and precious metals.Its good thermal conductivity keeps metal from cooling too rapidly. Made of natural flake graphite and silicon carbide bonded with find clay, lined with mullite for long life.
Our graphite crucibles are suitable for melting various metals as copper, gold ,silver, zinc, aluminium , lead .etc
