I wonder how many kinds of ceramics are there. What are their textures?
How are the ceramics classified? What classes can be divided into?There are many classifications of ceramics, which are generally classified according to the following four aspects:According to the use of points, can be divided into daily-use ceramics, art (display) ceramics, sanitary ceramics, building ceramics, electrical appliances, ceramics, electronic ceramics, chemical ceramics, textiles, ceramics, through thousands (gas transmission), ceramics and so onAccording to whether the glaze is applied, it can be divided into two categories: glazed ceramics and unglazed ceramics
Many kinds of special porcelain, a variety of oxide as the main body, such as high alumina porcelain, it is mainly to alumina, magnesia porcelain, Magnesium Oxide dominated; talc porcelain, porcelain with talc; beryllium or beryllium oxide, with beryl; zirconia ceramic, zirconia based on titanium porcelain with titanium oxide; mainly.The characteristics of the special porcelain is, by products not containing clay or contain very small amounts of clay, molding by dry pressing, high pressure method, in the defense industry, heavy industry in the use of such porcelain, such as rocket, baffle missile, aircraft, cars with spark plug in a semiconductor with radio. The rapid cutting of porcelain knife and so on.
The people in the production, research and Study on the convenience, and sometimes not according to the chemical composition, and according to the performance of ceramics, divided them into high strength ceramic, ferroelectric ceramic, acid resistant ceramics, high temperature ceramics, piezoelectric ceramics, high toughness ceramics, ceramic electrolyte, optical ceramics (i.e. transparent ceramics), magnetic ceramics, dielectric ceramics, magnetic ceramics and so on.It can be divided into three categories: hard porcelain, soft porcelain and special porcelainChina produced porcelain porcelain. Hard porcelain body composition, flux amount, high firing temperature, at 1360 DEG C to Zhijian color white, translucent, good strength, high chemical stability and thermal stability, and is a poor conductor of electricity, such as porcelain, high grade porcelain tableware, chemical porcelain, ordinary porcelain are such, also called feldspar porcelain.Soft and hard porcelain porcelain is different body containing flux more, firing temperature is slightly lower, at 1300 DEG C, so its chemical stability, mechanical strength, dielectric strength is low, the general industrial porcelain without soft porcelain, which is characterized by high translucency, more art porcelain, health porcelain, ceramic tiles and decorative porcelain, Bone China, porcelain frits usually belong to this category.
