The main function of alumina ceramic ring is to provide a growth and breeding environment for nitrifying bacteria, thereby improving water quality. So what are the advantages and disadvantages of alumina ceramic ring? Next, Pintejin Ceramics will introduce to you.
Alumina ceramics have low dielectric constant, low dielectric loss, high dielectric strength, high volume resistivity, good flexural strength, high stability, high compressive strength, and good thermal shock resistance.
It is widely used in thermostats, insulating parts, various thermal equipment, electric and electrical equipment, iron-structured buildings, shipbuilding, etc. of various small household appliances.
The advantages of alumina ceramic ring are high hardness, excellent wear resistance, corrosion resistance and high temperature resistance, good self-lubrication, and not easy to scale. Alumina ceramic parts have high hardness, high strength, low expansion coefficient, and insulation, wear resistance and corrosion resistance. They are used in machinery manufacturing, aerospace, precision instruments, petrochemicals, new light sources, textile machinery, electrical appliances, refrigeration equipment, electric heating instruments, Instruments, chemicals, communications, communications and other industries.
Alumina ceramic ring
The disadvantages of alumina ceramic rings are generally quite large elastic modulus, high hardness, high brittleness, and strong crack sensitivity. Therefore, the difficulty of machining is mainly manifested in machining hardness and machining brittleness.
Usually, the microstructure of alumina ceramics is equiaxed grains, which are polycrystalline structures composed of ionic bonds or covalent bonds, so the fracture toughness is low, under the action of external loads.
Stress will cause fine cracks on the ceramic surface, and the cracks will rapidly expand and cause brittle fracture. Therefore, during the machining and cutting of alumina ceramic rings, the phenomenon of chipping often occurs, that is, small cracks appear on the surface of the ceramic.
The above are the advantages and disadvantages of alumina ceramic rings brought to you by Pintejin Ceramics.
