Aluminium Nitride Ceramics

silicon nitride ceramics Silicon nitride ceramic is an inorganic material ceramic that does not shrink during sintering. The strength of silicon nitride is very high, especially hot-pressed silicon nitride, which is one of the hardest substances in the world. It has high strength, low density, high temperature resistance and other properties. High temperature resistance, the strength can be maintained to a high temperature of 1200 without decreasing, and will not melt into a molten body after being heated, and will not decompose until 1900 It has amazing chemical corrosion resistance, and can withstand almost all inorganic acids and less than 30% caustic soda solution, as well as many organic acids; It is also a high-performance electrical insulating material. Si3N4 can be used to manufacture ball bearings by virtue of its light weight and high rigidity. It has higher accuracy than metal bearings, generates less heat, and can operate in higher temperatures and corrosive media. The steam nozzle made of S ceramic has wear resistance, heat resistance and other characteristics, and it will not be obviously damaged after being used in 650 boiler for several months.

ceramic nozzle Material: zirconia Special size can be produced according to customer's drawings or samples Zirconia has high strength, wear resistance and flexibility, far surpassing most other technical ceramics. Zirconia is a very strong technical ceramic with excellent hardness, fracture toughness and corrosion resistance; The most common are Yttria partially stabilized zirconia (Y-PSZ) and magnesia partially stabilized zirconia (Mg-PSZ). Both of these materials provide excellent performance. Their unique crack propagation resistance and high thermal expansion make them excellent materials for connecting ceramics with steel and other metals. Because of its unique characteristics, zirconia is sometimes called "ceramic steel". In the field of structural ceramics, zirconia ceramics are widely used in the field of structural ceramics because of their high toughness and high performance. They are made of high strength and high toughness, high density, good wear resistance, high temperature and corrosion resistance, high stiffness, non-magnetic conductivity, electrical insulation, and high-temperature calcination and phase-separation technology at room temperature.

shaft sleeve material: silicon nitride Silicon nitride shaft sleeve, wear-resistant, impact resistant, hardness higher than steel Silicon nitride (Si3N4), is an important structural ceramic material. It is a kind of superhard material, which has lubricity and wear resistance, and is atomic crystal; Oxidation resistance at high temperature. Moreover, it can resist cold and hot shock, and it will not break when heated to 1000 or more in the air, and then cooled and heated sharply. It is precisely because silicon nitride ceramics have such excellent characteristics that people often use it to manufacture mechanical components such as bearings, gas turbine blades, mechanical seal rings, permanent molds, pump bushings, etc.

Honeycomb ceramic heat storage body has many remarkable advantages, such as high temperature resistance, corrosion resistance, good thermal shock stability, high strength, large heat storage capacity, good thermal conductivity, etc., and its energy-saving effect and service life are greatly improved. Regenerative high temperature air combustion is a new combustion technology with great energy saving and environmental protection effects. Honeycomb ceramic regenerator is the key component of regenerative burner, which is widely used in various furnaces, such as heating furnaces, hot blast furnaces, heat treatment furnaces, cracking furnaces, roasters, melting furnaces, soaking pits, oil and gas boilers, etc. in steel, machinery, building materials, chemistry, petrochemical, coating, non-ferrous metal smelting and other industries. This technology makes the two regenerators alternately absorb heat and release heat through the reversing device to maximize the heat recovery of flue gas, and then heats the combustion air and gas in the furnace to more than 1000 Even the inferior fuel with low calorific value can achieve stable ignition and efficient combustion, which can save fuel up to 25% - 30%, increase the output by more than 15%, reduce the oxidation burning loss of steel billet by more than 40%, and reduce the flue gas temperature of NOx emission less than 100 ppm to less than 150 The greenhouse effect of the earth's atmosphere has been greatly reduced. If most industrial kilns in the country adopt HTAC technology, its economic and social benefits are immeasurable, which will greatly alleviate the situation of energy shortage and greatly improve the living environment of human beings.
