Because of its chemical composition, microstructure and properties, new ceramics are called "new ceramics" or "special ceramics". The chemical composition and microstructure of new ceramics depends on the special nature and function it is different, such as high strength, high hardness, high toughness, corrosion resistance, conductivity, insulation, magnetism, light, semiconductor and photoelectric, piezoelectric, electro-optic, acousto-optic, magneto optical etc..

Because of their special properties, these ceramics can be used as engineering structural materials and functional materials for mechanical, electronic, chemical, smelting, energy, medical, laser, nuclear, aerospace, and other aspects. Some of the developed countries, especially in Japan, the United States and Western European countries, in order to accelerate the new technological revolution, the material foundation for the development of new industries, invest a lot of manpower, material and financial resources for research and development of special ceramics, so the development of new ceramics is very rapid, in technology is also a great breakthrough. The new ceramic is becoming more and more important in modern industrial technology, especially in the field of high technology and new technology.

New ceramic is developed in the twentieth Century, in promoting the modernization of science and technology and training, special ceramic "breeding" very fast, especially in recent thirty years, two new varieties of dazzling recently, emerge in an endless stream, due to the Fukushima earthquake and tsunami caused by the nuclear crisis of the nuclear reactor is used in the ceramic fuel and graphite structure material with high temperature resistance. Who will be the most profitable new type of ceramic in 2011? We'll wait and see......

1. Oxide ceramics

Alumina: it is one of the most widely used raw materials in new ceramic products, and has a series of excellent properties. In addition, it is also an important raw material for high temperature refractories, abrasives, abrasives, laser materials and alumina, precious stones and so on.

Zirconium oxide: it is an important material for high temperature structural ceramics, electronic ceramics and refractory materials.

Titanium dioxide: it is an important material for the manufacture of capacitors, ceramics, heat sensitive ceramics and piezoelectric ceramics.

BeO: it is an important raw material of high thermal conductivity ceramic model.

It is an important raw material of ferric oxide: strong magnetic material.

Two tin oxide: widely used in electronic ceramics.

Zinc Oxide: it can improve the mechanical and electrical properties of ceramic materials.

Nickel oxide: used in thermal sensitive ceramics.

Lead oxide: used in new ceramics as the main raw material for the synthesis of PbTiO3, Pb (Zr, Ti), O3, and Pb (Mg1/3, Nb2/3) O3.

Five oxidation two niobium: it is widely used in the electronic ceramic industry, such as the main raw materials for the manufacture of lead magnesium niobate, low temperature sintered monolithic capacitors, lithium niobate single crystals, and also can be used as modifying additives.

Manganese oxides: such as making humidity sensors, overheating protectors and so on.

Chromium oxide: used as a component of gas sensors and gas alarms.

Cobalt oxide: used in condensing materials.

2. Nitride ceramic

Boron nitride: its heat resistance, heat resistance, impact and high temperature strength, and can be processed into various shapes, so it is widely used as a processing material for various melts. Boron nitride powder and products have good lubricity, can be used as metal and ceramic filler, made of bearings. In addition, it is the smallest proportion of material in ceramic materials, so it is very beneficial to fly and structure materials.

Aluminum nitride: it has excellent electrical insulation and dielectric properties.

Silicon nitride: its products can resist various non corrosion of metal solution, can be used as a crucible, thermocouple protection tube, furnace lining materials, metal smelting furnace or heat treatment. It is an insulator and a dielectric body, can be applied to the integrated circuit, in addition, silicon nitride has high hardness, can be used as abrasive material, its thermal shock, is the manufacture of rocket nozzle and turbine blade suitable materials.
