What is the Ceramic ?

Ceramic clay raw materials, Barren raw materials and flux materials appropriate ratio, grinding, molding, and after a series of physical and chemical reactions in the case of high-temperature baking, the formation of a hard substance. Ceramic glazing and not glazing.

Glazing ceramic surface glaze is the nature of substances like glass, it is not only plays a decorative effect, but can also improve the mechanical strength of the ceramic, the performance of the surface hardness and resistance to chemical attack, while the glaze is smooth glass material, the pores rarely easy to clear dirt, convenience to use.



Below the glaze layer is a ceramics preform, the preform is generated after high temperature calcination crystal phase, a glass phase, quartz raw material does not participate in the reaction and stomatal group Sheng. Crystalline phase material is possible to improve the physical and chemical properties of the ceramic products, such as enhanced mechanical strength, abrasion resistance and thermal stability, etc., but it is poor translucent section rough. The glass phases substances filled in the crystal phase the substance around into a coherent whole and improve the overall performance of the ceramic, but the glass phase is a brittle, thermal stability and wear resistance is poor, so the glass phase to be controlled within a certain range.



The glass phase is possible to improve the light transmittance of the ceramic, so that the cross-sectional delicate. Not participate in the reaction quartz called free quartz preform containing a certain amount of free quartz performance between the body and the layer of glaze on the surface of it can be closer, better binding, but free quartz content is not too high, too high the poor thermal stability, causes the ceramic and difficulties bring to calcination. The stomatal exists among the ceramic, so that the refractive emitted reduced, reduction in strength, water absorption increases.



Thus making the formulation design, must take a variety of ingredients to figure out, to make the calcined ceramic containing various phase components to meet the requirements.
