Gold Melting High Temperature Crucible High Purity Boat Shape Acid Resistance

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.
