Product Description

Small silicon carbide graphiite crucible with spout lip for melting and transfering copper

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

Crucibles are widely used in the gold,silver,platinum and other noble metal's melting.
If it's used in oxygen atmosphere,it wil 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.


They are also 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.

Our silicon carbide graphite crucible has the following characteristics:
1.  Higher thermal conductivity: Shorten the time of smelting, save energy;
2. Higher strength: Shaped by isostatic pressing, internal structure without defects, high physical strength;
3.  Better oxidation resistance: Unique antioxidant design, and use high purity raw materials to protect graphite,
high oxidation resistance; It's 5~10 times of ordinary graphite crucible.
4.  Anti erosion: low porosity, special additives, effectively resist the corrosion of slag and other melts.
5.  long life: Crucible's life can be 3-5times longer than normal graphite crucible.
