The main difference of the relatively fine ceramics and traditional ceramics

Ceramics is quite common in our lives, the ceramics are many points, and today we want to compare what is the main difference between the next fine ceramics and traditional ceramics?
1, in the raw materials, breaking the traditional ceramic clay as the boundaries of the main raw material, special ceramics generally oxides, nitrides, silicides, borides, carbides, etc. as a main raw material. The main difference is that the fine ceramic raw material of various chemical composition, morphology, particle size and distribution can be precisely controlled.
Composition, traditional ceramic composition is determined by the composition of the clay, so different origin and different texture ceramic kiln. Since the special ceramic raw material is a pure compound, so the component is determined by manual ratio, the merits of its nature by the purity of raw materials and processes, rather than determined by the origin.
3, in the preparation process, forming the static pressure on the multi-use advanced injection molding and vapor deposition method, to obtain a uniform density distribution and relatively accurate body size, body density has improved greatly; break through the traditional sintering method ceramic kiln as the main means of production limits, widely used vacuum sintering, protective atmosphere sintering, hot pressing, hot isostatic pressing, reaction sintering and self-propagating high-temperature sintering means.
4, in the performance of special ceramics with different special nature and function, such as high strength, high hardness, corrosion resistance, electrical conductivity, insulating magnetic, electric, light, sound, bio-engineering, special features, so that a wide range of applications in all aspects of high temperature, mechanical, electronic, aerospace, medical engineering.
Fine ceramics and traditional ceramics, the fundamental difference is that from the selection of raw materials preparation and follow-up of the manufacturing process for the implementation of strict control, can be made to get the actual need of ceramic materials with different performance requirements.
