China has exquisite ceramic art and a long historical tradition in the world is rare, and always worthy of our admiration of later generations to learn and be proud of. Any use of clay and porcelain two different types of clay as raw material, ingredients, forming, drying, calcination process made objects, can be called pottery. Production of many types of ceramic raw materials, not only the pottery and porcelain are all kinds of pottery and ceramic raw materials there are many different properties and characteristics, texture and color are different. Most important is the clay and the clay, glaze, etc..
Introduction of new ceramic materials It is used in addition to the traditional ceramic mineral raw materials, are: 1, oxide raw materials a, alumina: it is a new type of ceramic products in one of the most widely used raw materials, with a series of excellent performance. In addition, it is high temperature refractories, abrasives, abrasive, laser materials and important raw materials such as aluminum oxide stones. b, zirconia: it is the high-temperature structural ceramics, electronic ceramics and refractories of the important raw material. c, titanium dioxide: it is the manufacturing ceramic capacitors, piezoelectric ceramics, thermal ceramics and important raw material products. d, beryllium oxide: it is a high thermal conductivity of the important new ceramic material. e, iron oxide: it is an important powerful magnetic material. f, tin dioxide: widely used in electronic ceramics. g, zinc oxide: it can make ceramic materials to improve mechanical and electrical properties. h, nickel oxide: used in thermal ceramics. i, lead oxide: mainly used in the synthesis of new ceramic PbTiO3, Pb (Zr, Ti) O3 and Pb (Mg1 / 3, Nb2 / 3) O3 of the main raw material. j, niobium oxide: in the electronic ceramics industry, it is widely used, such as used for manufacturing low-temperature sintering PMN monolithic capacitors, lithium niobate single crystal and other major raw materials, also available as a modified additive. k, manganese oxide: such as the production and humidity sensor, overheat protection device and so on. l, chromium oxide: as gas sensors, gas alarm batching. m, cobalt oxide: used in materials such as condenser. 2, complex oxide materials a, Titanates: There BaTiO3, SrTiO3, CaTiO3, MgTiO3 and PbTiO3, etc.. BaTiO3 is a piezoelectric, ferroelectric ceramics an important raw material. b, zirconium salt: There BaZrO3 and SrZrO3 so. Applied to core, oscillators. c, stannate: There BaSnO3, CaSnO3, InSnO3, CaSnO3, NiSnO3 and PbSnO3, such as CaSnO3 used in capacitors. d, niobate: There LiNbO3 and KnbO3. e, antimonate: There BaSb2O6, PbSb2O6 and MgSb2O6 so. f, aluminate: There MgAl2O4. g, aluminum silicate: There 3Al2O3o2SiO2. 3, rare earth oxide materials, such as: Yb2O3, Tu2O3, Nd2O3, Ce2O3, La2O3 so. 4, non-oxide materials a, carbide (1) titanium carbide: Tool to do so. (2) boron carbide: it is the metal-ceramic bearings, turning tools and other production materials. (3) Silicon carbide: SiC using a conductivity, used to manufacture high-temperature furnace used for heating materials and semiconductor materials. Silicon carbide with high hardness, good wear resistance, grinding performance, and a thermal shock resistance, anti-oxidation properties, it is very important for grinding material. Can also be used as a fire box and combustion chamber engine nozzle materials, and under high temperature turbine wheel, bearings and blades and other parts. b, nitride (1) boron nitride: its heat resistance, thermal shock and high temperature strength is high, but also processed into various shapes, it is widely used for a variety of melt processing of materials. Boron nitride powder and the products have good lubricity, can be used for metal and ceramic fillers, made of bearing. In addition, it is the smallest proportion of ceramic materials in the material, so for the flight and structural materials is very beneficial. (2) AlN: It has excellent electrical insulation and dielectric properties. (3) silicon nitride: its ability of various non-metallic products, the erosion of the solution can be used as a crucible, thermocouple protection tubes, furnace materials, metal melting furnace or heat treatment of the lining material. It is an insulator and dielectric body, can be used in integrated circuits, in addition, the high hardness of silicon nitride, can be used as abrasive material, its thermal shock is so great that manufacture rocket nozzles and turbine blades of a suitable material. c, boride (1) zirconium diboride: A zirconium diboride-based refractory material, resistant to molten tin, lead, copper, aluminum and other metal erosion, it can be used as the casting of metal smelting, crucible, plate etc.. ZrB12 has good thermal stability, with its casing made of continuous temperature measurement thermocouple can be used in the molten hot metal in 10-15 hours, in the melting of the molten steel (1700 ℃) hours of continuous use, in molten brass and copper used in 100 hours. d, silicide Such as molybdenum disilicide, can be in the air when the temperature reaches 1700 ℃ continue to use the thousands of hours, so in the supersonic aircraft, rockets, missiles, atomic energy industry has a range of uses
