Alumina Ceramic Main Raw Materials - Calcined Alumina
Calcined alumina still has high strength, high toughness, corrosion resistance, anti-wear, high insulating, and high chemical stability at high temperatures, and is the most hard substance only in the world.
During the production process, the three -dimensional space grows in the three -dimensional space and is a microcrystalline spherical and the size stability is good. Avant modified its surface during production, showing many unique and excellent properties, such as high purity, particle size distribution concentration, good dispersibility, fine particles, and crystallinity.
It can be widely used in the reinforcement of various plastic, coatings, rubber, ceramics, refractory materials and other products.
Alumina ceramics have highly high, hardness, chemical corrosion, excellent dielectric properties based on calcined alumina.
The effect of calcinedaluminum in ceramic is wear resistance, increase intensity, and form a surface composite coating.
This coating has improved the mechanical, physical and chemical properties on the surface of the substrate, and gives the substrate surface new mechanics, thermalism, optics, electromagnetics, and catalytic sensitivity to achieve the purpose of material surface modification and functionalization.
Calcined alumina material has special photoelectric characteristics, high magnetic resistance phenomenon, nonlinear resistance phenomenon. Under high temperature still has high strength, high toughness, good stability and other strange characteristics.
As well as a small size effect, surface interface effect, quantum dimensional effect, and macroscopic quantum tunnel effect, so alumina ceramics, high-temperature thermoelectric coupling tubes, chemical high-pressure mechanical pump parts, internal combustion engine Various ceramic devices such as spark plugs, artificial joints and aerospace generated materials. It has broad application prospects in the fields of catalytic, filters, light absorption, medicine, magnetic media and new materials.
