Why is industrial ceramic not transparent?
Industrial ceramic is a polycrystalline inorganic material, generally composed of grains, grain boundaries, pores and so on. In general, the opacity of ceramics is caused by the discontinuity of the refractive index between the grains due to the randomness of the non-equiaxed crystal grains in the alignment orientation, and the scattering caused by factors such as grain boundary effects and pores.
In the preparation of industrial ceramics, by using high-purity and ultra-fine raw materials, incorporating as few additives as possible and strict control of the process, the pores and impurities in the industrial ceramic materials are fully excluded and the crystal size of the ceramic materials is appropriately controlled. The article is brought close to the theoretical density, thereby preparing a transparent ceramic. In addition, the primary condition for preparing transparent ceramics is that the single crystals that make up the ceramic are transparent and have high symmetry at the same time. More alumina ceramic tubes are welcome to inquire!
