Graphite Crucible & Stopper – Important Tools for Gold Smelting & Casting

High purity, good thermal conductivity.
Corrosion resistance and strong oxidization resistance.
High Strength and stable quality.

3 sets of graphite crucible & stopper are placed on the desk.

Description

Graphite crucible & stopper are made of high purity graphite materials. Of which, graphite crucible is a vessel used for smelting precious metals, as well as casting and refining purposes. It is mainly used to smelt copper, brass, gold, silver, zinc, lead and other non-ferrous metals and their alloys. In the process of smelting gold in a crucible, the stopper can be used to control the opening and closing of the hole as well as the flow of molten liquids.

Crucible & stopper are important tools used in the process of gold smelting and casting. These tools can precisely control the smelting and casting processes to ensure that the gold is melted to the desired consistency and cast into the desired shapes.

Features

High purity graphite. 99.9% high purity graphite crucible, high density, fine and luster surface, and the crucible is not easy to be doped with impurities during the smelting process.
Great thermal conductivity. It heats fast and can greatly shorten the melting time and save energy.
Stable quality. It can be used normally even at high temperatures of 1800 °C, and can be used at high temperatures for a long time.
Stable performance. It can maintain stability even in strong acid and alkali environments, and is not easy to be corroded and oxidized.
Wide range of applications. It is widely used in the smelting of non-ferrous metals such as gold, silver, copper, aluminum, and lead.
