Description
Technical field
The present invention relates to a kind of crystalline ceramics, be specifically related to a kind of crystalline ceramics and preparation method thereof, belong to stupalith production technical field.
Background technology
General pottery is opaque, but optical ceramics is transparent as glass, therefore claim crystalline ceramics.General ceramic opaque reason is that its inside has impurity and pore, and the former can absorb light, and the latter makes light produce scattering, so just opaque.Therefore if select high pure raw material, and by process means, get rid of pore and just may obtain crystalline ceramics.Be exactly to adopt such way to obtain transparent alumina-ceramic in early days, work out successively afterwards as many oxide series crystalline ceramics such as sintering white fused alumina, magnesium oxide, beryllium oxide, yttrium oxide, yttrium oxide-zirconium dioxides.Develop again in the recent period Non-oxide Transparent Ceramics, as gallium arsenide, zinc sulphide, zinc selenide, magnesium fluoride, Calcium Fluoride (Fluorspan) etc.
Since R. L. Coble in 1962 reports first and has successfully prepared transparent alumina ceramic material, for stupalith has been opened up new Application Areas.This material not only has the good transparency, and corrosion-resistant, can under High Temperature High Pressure, work, also has the unrivaled character of many other materials, as high in intensity, dielectric properties are good, low conductivity, high heat conductance etc., so obtain increasingly extensive application river in fields such as lighting engineering, optics, extraordinary instrument manufacturing, wireless electron technology and high-temperature technologies gradually.Over nearly 38 years, many countries, the especially U.S., Japan, Britain, Russia, France etc. have done a large amount of research work to transparent ceramic material in the world, have successively developed A1
