Product Description

High-density graphite crucible

Graphite crucible, also known as molten copper bag, molten copper, etc., refers to a kind of crucible made of graphite, clay, silica and wax stone as raw materials.

Graphite crucible is mainly used to melt non-ferrous metals such as copper, brass, gold, silver, zinc and lead and their alloys..

Specification

Applications

1. High temperature resistance

2. Strong thermal conductivity

3. Good corrosion resistance

4. Long life

Key Configurations

1. Graphite crucible can be used for non-ferrous metal smelting and casting, melting aluminum, 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 jewelry industry. That requests graphite material has high density and purity, ablation-resistance, and it can be used many times. We can machine various crucibles according to 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 will 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.
