Siliconized graphite is a composite material in which silicon carbide is attached to the surface of a graphite substrate. It has the characteristics of high hardness, high mechanical strength and wear resistance of silicon carbide, as well as the self-lubricating properties and thermal shock resistance of graphite. It is an ideal friction materials and mechanical seal materials, suitable for mechanical sealing of various water pumps, oil pumps, chemical pumps, and bearings of various high-speed and high-load main pumps. In addition, siliconized graphite has good oxidation resistance, thermal shock resistance, low porosity, and certain electrical conductivity, and can be used as materials such as metal smelting crucibles and draft tubes.<\/p>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n

The composition of siliconized graphite is uniform, the surface is consistent with the inside, and the composition ratio of silicon carbide and graphite is adjustable. The higher the content of silicon carbide, the greater the density of the material, the higher the compressive strength, and the resistivity increases.<\/span><\/p>\n
