China Crucible Graphite Graphite Crucible

L.T Graphite has a comprehensive product and technology portfolio that focuses on four fields of graphite- ultrafine particle graphitemould, graphiteelectrode, graphite crucible, as well as other products mainly made of graphite.
Graphitematerials exhibit unique properties such as good electricaFiltration Equipment & Parts l and thermal conductivity, heat and corrosion resistance,low friction, and reduced weight while at the same time maintaining high strength. Due to the shortage of energy and raw materials, our high performance products made from graphiteare in increasingly high demand in industries. They also play a progressively important role in everyday life, thereby substituting traditional materials.

L.T Graphite crucible is divided into four categoriesIndustrial Brake : 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 ) Graphite cruciblehas good thermal conductivity and high temperature resistance, the use of high tempSecurity Guard erature, the thermal expansion coefficient is small, the rapid heat, quenching has a certain anti-strain properties. Right acid, alkaline solution, strong corrosion resistance, with excellent chemical stability.

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.

d. Graphite crucible for vacuum coating of gasification aluminum for example.
Is mainly suitable for under the condition of vacuum, the metal aluminum gasificationand 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 wiOther Bags & Cases ll 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 lifeof the crucibleis prolonged.
