Graphite Crucibles

      Unique Properties of graphite crucible such as good thermal conductivity, high temperature resistance, corrosion resistance to acid and alkaline and much lower thermal expansion coefficient than other materials.

     Due to its excellent performance, graphite crucible is widely used in metallurgy, casting, machinery, chemical and other industrial sectors for the smelting of alloy tool steel and the smelting of  non-ferrous metals and their alloys, and has good technical and economic effects.

     L.T Graphite crucible is divided into four categories: high purity fine particle graphite crucible, medium  particle graphite crucible, silicon carbide graphite crucible and  other coated graphite crucible( graphite crucible for vacuum coating of gasification aluminum )

  Four categories graphite crucible and Tech Data:

a. High purity fine particle graphite crucible


b.  Medium particle graphite crucible


c.  Silicon carbide graphite crucible



Silicon Carbide (SiC) Crucibles are high quality melting crucibles. Suitable for smelting non-ferrous metals such as gold, silver, brass, copper, aluminum, lead and zinc; Medium carbon steel and various rare metals.

Service life:

Depends on which materials to melting, normally Isostatic pressing silicon carbide graphite crucible service life is two times more than normal spin forming sic graphite crucibles(graphite clay crucibles).

 For example, melting brass: graphite clay crucibles can use 50 shots around.

Isostatic Pressing silicon carbide graphite crucible can use more than 100 shots.

 d.  Coated graphite crucible
     Graphite crucible for vacuum coating of gasification aluminum for example.
     Is mainly suitable for under the condition of vacuum, the metal aluminum gasification and evaporation on the surface of CPP, PET, BOPP film,        And forming aluminum composite film. Graphite crucibles are a large number of consumption parts during the producing process, the quality of graphite crucibles will directly affect the product quality and production cost of aluminum plating film.
      L.T graphite has developed a new kind graphite composite materials, used for vacuum coating of gasification aluminum, with outstanding features: greatly improve its oxidation resistance, high bulk density and flexural compressive strength, increased abrasion resistance and hardness, reduce porosity and permeability. The wetting and erosion ability of molten aluminum liquid and gaseous aluminum molecules is weakened to a large extent, and thus the service life of the crucible is prolonged.
