Silicon carbide, commonly alumina c799 known as emery, is generally made by the electric reaction after mixing silica and coke. Silicon carbide is composed of sic, which takes on green, black and yellow colors due to impurities. Industrially, it is divided into two categories according to color, silicon carbide and silicon black, and its sic content is ≥99% and 98.5%, respectively.
Silicon carbide is a covalent bond compound with strong interatomic binding 7g Ozone Generator force, high melting point, high hardness, high strength and low expansion, high thermal conductivity, high conductivity, and reinforcement stability, so it is a good refractory raw material. However, under an oxidizing atmosphere, silicon carbide is easily oxidized.
Performance: with excellent mechanical properties at room temperature, high energy bending strength, excellent oxidation resistance, good corrosion resistance, high wear resistance and low friction coefficient, its high temperature strength can be maintained until 1600C, is the best high temperature strength of ceramic materials, oxidation resistance is also the best of all non-oxide ceramics.
Advantages: Silicon carbide ceramics have excellent high temperature creep resistance, and have 10g Ozone Generator semiconductor properties, the incorporation of a small amount of impurities will show good conductivity, processing can obtain a mirror effect.
Disadvantages: The disadvantage of silicon carbide ceramics is that the fracture toughness is low, that is, the brittleness is larger.Application: Widely used in large blast furnace lining; Mechanical sealing rings, de-metal burring knives, etc. There are many differences between silicon carbide ceramics and silicon nitride 3500mg Ozone ceramic Plate ceramics, and today I will say this, and the follow-up will continue to share!
