High-purity graphite is a material carbon content more than 99.9%, that contains extremely low levels of impurities. High-purity graphite has the characteristics of high temperature oxidation resistance, good electrical conductivity, good chemical stability, and good insulation performance. It is a graphite material with high crystallinity and high purity, which can be used in various applications:
In the electronics industry, it can be used to manufacture electrodes, conductive plates, heat dissipation plates, vacuum furnaces, anti-static materials, heat insulation materials for high-temperature furnaces, etc.
In the metallurgical industry, high-purity graphite can be used to manufacture graphite molds, graphite casting tubes, graphite vibrating rods, etc.
In the chemical industry, it can be used to manufacture sealing materials, valves, pumps, pipes, etc. of chemical equipment.
In the machinery manufacturing industry, high-purity graphite can be used to manufacture machine tool guide rails, bearings, steel rolling rolls and other components.
In the field of aerospace, high-purity graphite can be used to manufacture engine parts, conductive materials, heat insulation materials, etc.
In the nuclear industry, high-purity graphite can be used to manufacture graphite cores in reactors, graphite heat exchangers, etc.
In the field of medical devices, high-purity graphite can be used to manufacture artificial heart valves, electrodes, etc.
It is believed that high-purity graphite will also be applied in many unknown fields, waiting for our exploration.
Our company currently produces 8 grades of high-purity graphite raw materials to supply the processing of our high-purity graphite series end products. We will recommend the most suitable high-purity graphite material according to the customer's specific application scenarios and technical parameter requirements. The control of the entire production line from raw materials to end products is also an important factor for the quality assurance of our products.

our high-purity graphite materials are divided into three categories according to different production methods:
Molded high-purity graphite. Molded graphite has a wide range of properties in terms of mechanical strength, friction resistance, density, hardness, electrical conductivity, etc., and can be further developed by impregnating resin or metal.
High-purity graphite formed by isostatic pressing. Isotropic graphite with fine particle cold isostatic pressing has the following characteristics: good electrical and thermal conductivity, high strength at high temperature, small coefficient of thermal expansion, self-lubricating, high temperature resistance, acid, alkali and salt resistance, corrosion resistance, high bulk density, easy processing, etc. . It has been widely used in industry, such as monocrystalline silicon drawing, polycrystalline silicon production and ingot casting, electric discharge machining, metal continuous casting, precious metal smelting, vacuum furnace, high temperature corrosion-resistant container and the characteristics of this product Other related purposes, etc.
Extruded high-purity graphite. It can be used in hot pressing molds, ordinary casting molds, centrifugal casting molds, die-casting molds, etc. Performance: heat resistance, chemical corrosion resistance, good thermal conductivity, low thermal expansion coefficient, and low wettability to molten metal.
