How alumina ceramics beat metalThe new generation of industrial parts is alumina ceramics, which will replace traditional metal parts, because ceramics have good performance and high availability, which can further improve the performance of the machine.High-purity alumina ceramics can be made into
Each of the factors will affect the firing of zirconia ceramics, as well as several main factors affecting the firing of zirconia ceramics: degreasing stage, raw powder, additives, sintering temperature and time, pressure and sintering atmosphere.
The application of rare earths and rare earth oxides in ceramic materials is mainly used as additives to improve the sintering, compactness, microstructure and crystal phase composition of ceramic materials, thereby greatly improving their mechanics and electrical , Optical or thermal properties to meet the performance requirements of ceramic materials used in different occasions. This article briefly reviews the application of rare earth oxides in structural ceramic materials and functional ceramics.
At present, the brittleness of ceramic materials is one of the main factors restricting its development, so toughening has become a core issue in the field of ceramic materials research. The method of toughening zirconia is mainly achieved by the phase change of zirconia!
Zirconia ceramic ring mirror polishing is a kind of ceramic flat polishing process, and its main material is zirconia. Pure zirconia is generally white, and appears yellow or gray when it contains impurities. Due to its characteristics, zirconia ceramic rings will have many problems in the processin
Zirconia ceramics are also widely used in parts and accessories, and the quality requirements and dimensions of different parts are different. So what are the requirements for zirconia ceramics when using bearings for electric machine? Let me introduce to you what are the requirements for zirconia c
First, friends who know zirconia ceramics should know that it has a very hard shell, and its hardness is close to that of natural diamonds, but it is much lighter than metal in weight, and more importantly, it will never wear and change color. Therefore, many high-end watches are made of zirconia ce
Zirconia is a white, powdered metal oxide. Like other common dental crown materials, it is a ceramic. Zirconia is made from zirconium, a metal with similar properties to titanium. Zirconia ceramics, ZrO2 (zirconium dioxide) ceramics, have high melting and boiling points, high hardness, insulators a
Q : Does alumina ceramic absorb water?A : Whether the ceramic absorbs water is judged whether it is processed by high temperature sintering process, usually the water absorption rate of ceramic is ≥5%. Q : Is alumina ceramic conductive?A: AI2O3 ceramics have excellent electrical insulation performa
