Good Thermal Conductivity High Temperature Crucible / Graphite
Crucible
Performance:
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 system will fully ensure the
stability of quality.

Note: for machined graphite products, usually we have the following
series:
1.)For non-ferrous metallurgy and processing
2.)For sintering mold of diamond tools
3.)For electron and semiconductor industry
4.)For application of processing by industrial furnace under high
temperature
5.)For mechanical industry
Others: especially requested by users, we can produce it as per
user’s drawing, samples or other kind of request
Application :
1. )Graphite crucible can be used for non-ferrous metal smelting
and casting, 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 jewelryindustry. That requests graphite
material has high density and purity, ablation-resistance, and it
can be used many times. We can machine various crucibles
accordingto 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 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.
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
