Ceramic valves are usually produced and processed using industrial alumina and zirconia ceramic materials, and their properties are often used in harsh conditions. Ceramic valves are installed on heavy process pipelines, and the working conditions are complex. Once a problem occurs, it is often helpless because of its heavy weight and difficult to pinpoint. It also involves system commissioning, system integrity, adjustment quality, environmental pollution and other issues. Therefore, the rational use of ceramic valves to maintain them to the maximum extent and prolong their service life is the primary problem of using ceramic valves. The following five methods for prolonging the life of ceramic control valves are provided by Read more

The above introduces a method of chemical stabilization of zirconia ceramics to avoid internal crystal phase transformation. Next, Pintejin Ceramics will continue to explain another physical stabilization method. Physical Stabilization When the tetragonal crystal phase of ZrO2 particles transforms to monoclinic phase, and is partially or completely cut off by the surrounding matrix phase, the physical stabilization effect is obtained. The mechanically stable and compact structure formed by the matrix almost completely suppressed the volume expansion of ZrO2 crystals, so the tetragonal phase maintained a metastable state. When PSZ contains tetragonal crystal phase, it is considered as toughening ZrO2. Tetragonal ZrO2 ginseng crystals can be prepared by sintering ZrO2 fines Read more

What are the properties of alumina ceramics? Alumina ceramics are often used in industrial industries. Pintejin Ceramics Factory is a manufacturer of ceramic parts.

Generally speaking, structural ceramics refer to the ceramics used in the manufacture of mechanical equipment and machining tools in various industrial sectors. What are the commonly used ceramic materials in structural ceramics? Next, Pintejin ceramics will introduce to you.   1. Zirconia ceramics Zirconia ceramics are white, yellow or gray when containing impurities, generally containing HfO2. It is not easy to separate. There are three crystalline states of pure ZrO2 under normal pressure.   The production of zirconia ceramics requires the preparation of powders with high purity, good dispersion properties, ultra-fine particles and narrow particle size distribution. Zirconia ceramics have high toughness, high flexural strength and high wear resistance, excellent Read more

Due to the high hardness, brittleness and low thermal conductivity of ceramic materials, it is a kind of difficult-to-machine material, so ceramic precision cutting has appeared. The following is introduced by Pintejin Ceramics. Difficulties in cutting zirconia ceramic precision cutting knife ceramic precision ceramics: Ceramics have high hardness, such as alumina ceramics, titanium carbide ceramics, the hardness can reach HV2250-3000, higher than cemented carbide, second only to diamond and cubic Boron nitride has high wear resistance, and in the process of precision ceramic cutting, the precision and roughness of the ceramic surface to be cut have certain requirements, which cannot be processed by ordinary machining methods. What is the machine Read more
