2. Graphite crucible Application
Used in furnaces for production of special ceramics products, such
as boron carbide , boron nitride products.
High pure graphite crucible is widely used in casting, smelting,
mould.
High precision CNC machines can realize the production of high
pure, high dense, high strong
graphite crucible for continuous casting, graphite moulds for
electronics, graphite moulds for
smelting, other processed graphite products with various shapes for
different applications, and
can process precise and rough graphite.
All products are made of isostatic, high pure, high dense and high
strong graphite. The finished
products include high pure graphite crucibles, graphite rods,
graphite covers, graphite coils and
so on, with high performance.
3. Characteristics
1. Thermal stability: According to the quench acute thermal using
conditions of graphite crucible,
we will specially design the production procedure, so as to ensure
the reliability of product quality.
2. Corrosion resistance: Even and fine basic design will delay the
erosion of crucible.
3. Impact resistance: Graphite crucible can bear high thermal
impact, so any process can be carried
out.
4. Acid resistance: The adding of special materials will greatly
improve the quality of crucible,
especially its index of acid resistance., and will prolong the
service life of graphite crucible.
5. High heat Conduction: High content of fixed carbon ensures the
good heat conduction, shorten
the time of dissolution, and remarkably reduce the energy
consumption.
6. Control of metal pollution: The component of material under
strict control will ensure that graphite
crucible will not pollute the metals when dissolving.
7. Quality stability: The process technology of forming under high
pressure and quality guarantee s
ystem will fully ensure the stability of quality
4. Advantage
- high strength (Flexural strength: 39Mpa Compressive strength: 78Mpa
With rising of temperature, graphite strength increases)
- high purity (Carbon: 99.5%)
- high temperature resistance (graphite material melting point is
3850±50)
- good heat shock resistance.
