Isostatic Graphite Crucible

VeTek semiconductor Isostatic Graphite Crucible is typically crafted from high-purity graphite materials. These graphites are engineered to exhibit exceptional thermal stability, resistance to chemical corrosion, and thermal expansion properties.VeTek semiconductor Isostatic Graphite Crucible composition ensures it can withstand the extreme conditions encountered during high-temperature processing.

Graphite Crucible is precision-engineered to withstand the demanding conditions of semiconductor manufacturing processes. They feature a robust, cylindrical shape with a smooth interior surface to facilitate uniform heat distribution and crystal growth. 

Core characteristics

✔ Excellent high temperature resistance

The maximum tolerance temperature is above 1600°C, which can be used for long-term stability in melting gold, silver, aluminum, copper and other metals.

Low porosity (≤30%) and high density (2.30g/cm³) effectively resist penetration and chemical erosion of molten metals.

✔ Excellent thermal shock resistance

The isostatic pressing process endows the material with isotropy, avoids rupture due to sudden temperature changes, and extends the service life.

✔ High mechanical strength and thermal conductivity

The uniform grain structure provides high strength support while rapidly conducting heat and improving melting efficiency.

✔ Customized design

Support different size customization, suitable for centrifugal casting, induction furnace and other equipment.

Typical application scenarios

✔ Metalworking industry

Gold, silver and other precious metals purification; Aluminum alloy, copper alloy melting and casting.

✔ Pyrochemical treatment

Corrosion resistant vessels in semiconductor material preparation and glass melting process.

✔ Precision casting

Molding carrier for jewelry mold and diamond tool sintering mold

✔ Semiconductor

the growth of monocrystalline silicon ingots via techniques such as Czochralski and float-zone methods
