Ceramic heating plate product features introduction!
Special ceramic heating plate
The performance of special ceramic materials is determined by two factors. First, the material structure, the main chemical bond properties, the crystal structure. They determine the properties of ceramic materials, such as high temperature resistance, semiconductivity and insulation. Secondly, the microstructure, including distribution, grain size, shape, pore size distribution, impurities, defects, etc. Ordinary ceramics are made of clay, feldspar, and quartz as raw materials, which are prepared and sintered. This kind of ceramics is hard in texture, does not oxidize and rust, is corrosion-resistant, does not conduct electricity, can withstand a certain high temperature, has good processability and low cost, but has low strength. Generally, the maximum operating temperature does not exceed 1200 degrees Celsius. This type of ceramic has a large output and a variety of types, and is widely used in electrical, chemical and other industries.
Ceramic heating plate
Silicon carbide powder used for silicon carbide ceramics is made by powder metallurgy through reaction sintering or hot pressing sintering process. The biggest features of silicon carbide ceramics are high-temperature strength, good thermal stability, and good wear resistance and creep resistance. Suitable for casting metal throat nozzles, thermocouple sleeves, gas turbine blades, bearings and other parts. At the same time, because of its high thermal conductivity, it is also suitable for heat exchanger materials under high temperature conditions, and can also be used to make various pump seals.
Silicon nitride ceramics are rich in raw materials and good in processability, and can produce various size accurate parts at low cost, especially parts with complex shapes, and the yield is higher than other ceramic materials. Silicon nitride ceramics have good resistance to rapid temperature changes and high hardness. Its hardness is second only to substances such as diamond and boron nitride. The engine is made of silicon nitride ceramic materials. As the operating temperature is increased to 1370 degrees Celsius, the engine efficiency can be increased by 30%. At the same time, due to the increase in temperature, the fuel can be fully burned, and the pollutant components of the exhaust gas will be greatly reduced, which not only reduces energy consumption, but also reduces environmental pollution.
There are many other special ceramic materials. They have their own characteristics and can be made into various functional components. Lithium oxide ceramics are high-temperature materials, talc ceramics are high-frequency insulating materials, thorium oxide ceramics are dielectric materials, barium titanate ceramics are optoelectronic materials, and cermets such as borides, nitrides, and silicides are ultra-high-temperature materials. Ferrite ceramics are materials such as permanent magnets, memory magnets, magnetic heads, rare earth cobalt porcelains are memory materials, and semiconductor porcelains are materials such as sub-sensitive elements, solar cells, etc.
