Advanced ceramic, also popularly known as technical ceramic or engineering ceramic around the world, is a high-tech material in modern world. Advanced ceramic fiber has been of great popularity in recent years for its extraordinary properties and it has helped to drive industrial development. So, what is special about this newly appeared material? What are the characteristics of advanced ceramic fiber? In this passage, some introduction and illustration will be provided.
- What is advanced ceramic
- Classification of advanced ceramic
- The properties of advanced ceramic
- Applications of advanced ceramic
Using the methods of contemporary material science, new materials or new combinations of existing materials have been designed. The newly manufactured material, such as advanced ceramic, has shown surprising changes in the properties of traditional ceramics. The development of advanced ceramic technology continues to improve rapidly. These inorganic and non-metallic material is leading to a revolution in the types of materials and properties obtained. Today, there are a variety of advanced ceramics, including alumina, zirconia, silicon nitride, silicon carbide and so on. Each with its own unique characteristics and advantages.
Advanced ceramic fibers can be divided into three main types according to their chemical properties: oxides advanced ceramic, non-oxides advanced ceramic and composites advanced ceramic.
Oxide ceramics include alumina and zirconia; carbides, nitrides and silicide are in non-oxide ceramics group; composites have particulate reinforced and combinations of oxides and non-oxides.
Generally speaking, advanced ceramic fiber shows excellent properties, making them possess high corrosion resistance, abrasion resistance, thermal resistance and good flexibility. Advanced ceramic fiber usually has properties of high strength, stability, thermal resistance, chemical inertness and good electrical conductivity. Advanced ceramics also have suitable use for mass production, making them one of the most widely used material groups nowadays.
Advanced ceramic fiber usually lacks vitreous ingredients. In other words, they are "basically crystallized". The microstructure of advanced ceramic fiber is often highly engineered, which means that the size and shape of the crystalline particle, the porosity and phase distribution are carefully planned and controlled. Advanced ceramics often show unique or advantageous characteristics in functions, which can be "accurately specified" through careful processing and quality control. To be more specific, examples of advanced ceramic fiber include superconductivity and low thermal conductivity.
Advanced ceramic fiber is used mainly at the time when other material reaches its limits, such as in extremely high temperatures or under large compression force. Sometimes people even combine advanced ceramics with metals in order to optimize the characteristics as well as the performance of the material.
In summary, as advanced ceramic fiber exhibits excellent properties, it is popularly employed in a variety of industrial manufacturing processes ranging from heat engines to communication and energy transmission. Advanced ceramics are gradually taking the places of conventional materials, such as glass, bricks and plastics, so that the manufacturing process would be economical as well as energy saving.
