Product Description

Product Description

Graphite Foundry Crucibles or Clay Gray Crucible  are made from a combination of graphite and clay, these crucibles are recommended for melting your precious, or non-precious metals and can handle large batches of material. Their thick inner walls can handle direct heat and open flame foundries. Rated to withstand temperatures up to 850ºC-1600ºC.

Silicon carbide graphite crucible is a scientific mixture of silicon carbide and natural graphite powder, made by isostatic pressing and sintering. It combines the high temperature resistance of graphite crucible with its anti-oxidation and corrosion resistance, effectively reducing production costs. Excellent performance below 1700ºC

1.Designed for Melting Gold, Silver, Copper, Brass, Aluminum, and more...
2.Designed to use with Fuel and Medium/High-Heat Induction Furnaces and Kilns
3.Custom size crucibles are also available

Advantages of Graphite Crucible:
1. Excellent thermal shock resistance
2. High temperature resistance
3. Good chemical stability
4. Strong thermal conductivity

Application

1. Graphite crucible can be used for non-ferrous metal smelting and casting, melting aluminum, dissolving gold or silver ornaments, analysis of special type steel, sintering hard metal.


2. Graphite crucible for smelting gold is specialized in melting gold in headgear and jewelry industry. That requests graphite material has high density and purity, ablation-resistance, and it can be used many times. We can machine various crucibles according to customer's requirement. 


3. Machined from high pure graphite and widely used in the gold,silver,platinum and other noble metal's melting.If it's used in oxygen atmosphere,it will start to be oxygenized when the temperature is higher than 700-800°c. If it's used in the protective atmosphere, it can stand more than 2000°c.


4. Widely used in such fields as industrial furnaces, mono-crystalline silicon machinery, mono-crystalline silicon machinery, electron, semi-conductor, metallurgy, oil, chemistry, textile, electrical machinery, electrical equipment, electrical furnace, traffic, communication industry, medicine, etc.
