Led Ceramic Ornaments

Generally, Led Ceramic Ornaments are opaque, but optical ceramics are as transparent as glass, so they are called transparent ceramics. The reason why ceramics are generally opaque is that there are impurities and pores inside, the former can absorb light, and the latter scatters light, so it is opaque. Therefore, if high-purity raw materials are selected and pores are eliminated by technological means, transparent ceramics may be obtained. In the early days, this method was used to obtain transparent alumina ceramics, and later a variety of oxide series transparent ceramics such as sintered white corundum, magnesium oxide, beryllium oxide, yttrium oxide, yttrium-zirconia and so on were developed. Recently, non-oxide transparent ceramics have been developed, such as gallium arsenide, zinc sulfide, zinc selenide, magnesium fluoride, calcium fluoride, etc.
