Alumina Ceramics:
Alumina Ceramic colorants on the glaze surface are prone to the problem of dissolution of metal compounds in the colorants; the glaze technology is between the on-glaze color and the under-glaze color [firing temperature is 1100-1200 degrees]. The particles are in the middle of the glaze layer, the color tone forms a hazy beauty, but the type of colorant used is also limited; the coloring porcelain tire uses the colorant to be blended into the blank, so that the product porcelain has an excellent effect. The surface of the porcelain tire is generally transparent glaze; the color glaze is to introduce the colorant and pigment directly into the glaze to make the glaze to form a color glaze [firing temperature is 1150-1280 degrees]; there is also a colorant added to insoluble kaolin It is made of pottery [also known as makeup soil] for the decoration of ceramic products. It is called color makeup soil. This makeup soil can cover the unclean slabs of tiles and has a great effect. But still need to apply a layer of transparent glaze [firing temperature 1150-1250 degrees] on the surface of the color makeup soil to increase protection and brightness.
In practical use, various ceramic colorants and pigments have different firing ranges. Excessively high or low temperatures will adversely affect the color formation. Some pigments have a wide firing range, such as chrome tin red, aquamarine and the like. It can be used for both high-temperature under-glaze color firing and low-glaze color firing. Both of them have good color results. Some pigments have a fixed color range, which is taboo when used. For example, lead antimony pigments can only be used for the decoration of glaze and low-temperature glaze products. If the temperature exceeds the temperature, the color will be lost. In addition to the firing temperature, there are quite a few colorants and pigments that are very sensitive to the flame atmosphere in the kiln during firing, such as copper oxide pigments, which appear green when the flame is oxidized and red when the flame is reduced. The changes are huge.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
