Alumina ceramic valves offer many advantages over metal valves
Alumina ceramic is a kind of ceramic material with alumina as the main material, which is manufactured through specific work. Due to its excellent conductivity, high temperature resistance and mechanical strength, alumina ceramic is mainly used in thick film integrated circuits.
Alumina ceramics is further processed into a variety of alumina ceramic parts, valve is one of them, although the metal valve through the improvement of structure and material, have greatly improved, but restricted by metal material properties, can not adapt to more and more high wear, strong corrosive condition of demand, thus show the short service life, revealed serious problems, such as, greatly affect the stability of the system operation.
After replacing the metal valve with alumina ceramic valve, the above series of problems have been properly solved, which is because the ceramic material has very small thermal deformation, light weight, and much higher bonding strength than the metal, with excellent corrosion resistance, so it can better adapt to high wear, strong corrosion and other adverse conditions.
Generally, the crystal ion radius of alumina ceramic material is small, and the ion electricity price is high and the coordination number is large. These intrinsic properties determine the compressive strength, wear resistance and hardness of ceramic material.Although the "brittleness" of ceramic material itself and its difficulty in precision machining limit its application scope, the development and progress of martensite phase change toughening technology, composite material technology and nano-ceramic concept have greatly improved alumina ceramics and greatly improved its toughness and strength.
In addition, grinding technology has also improved, so that alumina ceramic valves can be better shape, and products in petroleum, chemical, mechanical and other fields more widely used, as an ideal substitute for traditional metal valves.
