Products Description

Features & Details
【HIGH PURITY GRAPHITE】- With 99.9% high-purity graphite and 1.8-1.9g/cm³ high density, our crucible is not easy to be doped with
impurities during the smelting process and can be used to melting high-purity precious metals.
【GREAT THERMAL CONDUCTIVITY】- This small graphite crucible has excellent thermal conductivity properties, which can highly shorten the melting time and save energy.
【RELIABLE QUALITY】- Using high-quality craftsmanship, our graphite furnace can be used up to a maximum temperature of 1300℃. Not easy to crack during high-temperature casting, long service life. Pour opening groove design makes it easy to use.
【STABLE PROPERTIES】- Compared to clay graphite crucibles, our high-purity graphite crucibles can still maintain stability when exposed to
strong acids and alkalis and are not prone to be corroded and oxidized.
【WIDE APPLICATION】- In metallurgy, foundry, machinery, chemical, and other industrial sectors, graphite crucibles are widely used in non-ferrous metal smelting, such as gold, silver, copper, aluminum, and lead.

Graphite Crucible Feature and Advantage

Stable Performance
High-quality materials and processes make our graphite crucibles have excellent stability and avoid extreme corrosion and oxidation.
Great Thermostability
Our graphite crucible can be used normally even at a high temperature of 1300℃. Not afraid of high temperature for more prolonged use.
Up to 3000℃ at inert gas or vacumn environment
Rapid Heating
With outstanding thermal conductivity, the graphite crucible can heat up quickly, saving time and energy.

99.9% Pure Graphite
Unlike other ordinary graphite crucibles, our high-purity graphite crucible has high density also a delicate and shiny surface.
Versatile Usage
This high-purity graphite crucible that can be used in metal smelting furnaces is ideal for melting gold, silver, copper, iron, aluminum, and other non-ferrous metals.
Easy to Use
Thanks to the dumping groove design, the graphite crucible for melting metal is more convenient to use.
