Graphite crucible for melting gold

  The Graphite crucible, which is divided into general type of graphite crucible, special type of graphite crucible, high purity graphite crucible.Graphite crucible, which is divided into general type of graphite crucible, special type of graphite crucible, high purity graphite crucible.The main raw materials of Graphite crucible is natural crystalline graphite. Therefore, it maintains the original natural graphite various physical and chemical properties.

  Graphite crucible has good thermal conductivity and high temperature resistance;Uder the high temperature, the thermal expansion coefficient is small, rapid heating, quench with certain anti-strain properties. The strong corrosion resistance of acid, alkaline solution has excellent chemical stability. Graphite crucible, with their more excellent performance, in metallurgy, casting,mechanical, chemical and other industrial sectors, is widely used in smelting and alloy tool steel smelting of non-ferrous metals and their alloys . Besides,it has achieved a good technical and economic results.

  Graphite crucible 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.

  Graphite crucible used 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.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.

  The graphite crucibles are 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.
