Reputation depends on quality, quality comes from Hard!
Silicon Nitride Ceramic:
The mineral components of flux raw materials are mainly oxides and oxygen-containing salts of alkali metals and alkaline earth metals. Such as feldspar, limestone, dolomite, talc, lepidolite, granite, etc. They play a fluxing role in production. After high-temperature melting, they can dissolve a part of the decomposition products of quartz and Gaoling clay. The high-viscosity glass after melting can play a high-temperature cementing effect. It also reduces viscosity at room temperature. In addition to the above three types of raw materials, other raw materials and auxiliary raw materials are collectively referred to as functional raw materials. Such as zinc oxide, zircon, pigment, electrolyte, etc. They do not play a major role in production, nor are they necessary ingredients for porcelain. Generally, a small amount of addition can significantly improve the performance of certain aspects of the product. Sometimes it is to improve the process performance of the blank glaze without affecting the performance of the product. Conducive to the realization of the production process. After the raw materials are selected, determining the amount of various raw materials used in the blank and glaze is a key task, because it is directly related to the quality of the product and the formulation of the process system. The design of the blank formula is a heavy and complicated task. At present, ceramic products are changing with each passing day, and the performance requirements of ceramic products are ever-changing. Moreover, there are many kinds of raw materials used in ceramic production, and there are big differences in chemical composition, mineral composition and their process performance, and the standardization of raw materials cannot be achieved. The differences in technology, equipment, and management levels of enterprises in various regions, as well as the performance indicators of ceramic products, are affected by many factors. Therefore, when designing blank formulations, you cannot rely on theoretical calculations, otherwise, it will be difficult to obtain satisfactory results. .
properties:
High hardness, high strength, wear resistance, corrosion resistance, high temperature(1200°), good thermal diffusivity, good thermal shock resistance(avoid the temperature changing rapidly), good insulativity, low density. The comprehensive properties are best in most of structure ceramic.
