Most ceramic products are basically white, and the color of alumina ceramics is of course the same. But for what reason, these ceramic products will turn from white castings to light yellow after a long time of use. Is it because the color of the alumina ceramics has changed? Of course not, the Pintejin Ceramics Factory will give you a detailed introduction. !Alumina ceramic rod The reason why the color of alumina ceramics is white and gradually becomes light yellow is because the internal composition changes after sunlight exposure, and this change is irreversible, so the color will also change. On the other hand, it may be that the alumina Read more

Structural ceramic materials are divided into two categories: structural materials and functional materials. When a material mainly uses its mechanical properties, this material is called a structural material. If it mainly uses its non-mechanical properties, it is called a functional material. In the literature, functional materials are often defined as “materials that utilize their physical properties”. From the perspective of discipline classification, physical properties are relative to chemical properties, mechanical properties are included in physical properties, and functional materials include chemical functional materials. Appropriately, mechanical properties usually refer to strength, plasticity, toughness, elasticity, hardness, fatigue, etc.; non-mechanical properties mainly refer to sound, electricity, time, magnetism, and chemistry. Structural Ceramics For Read more

Zirconia ceramic laser machining uses a uniform laser beam with high energy density (108-1O10W/cm2) as a heat source to generate instantaneous high temperature at a local point on the surface of the processed ceramic material, and local point melting or gasification to remove the material. Laser machining is a non-contact and frictionless machining technology. No mold is required in the machining process. By controlling the focusing position of the laser beam on the surface of the ceramic material, the machining of three-dimensional complex shape materials is realized. Ceramic laser machining is suitable for micro-drilling, micro-cutting, and micro-structure fabrication on inorganic materials such as organics and ceramics. At present, micro-holes with Read more

Zirconia ceramics have excellent properties such as high melting point and boiling point, high hardness, good toughness, good wear resistance, insulators at room temperature, and electrical conductivity at high temperatures. What are the machining processes of zirconia ceramics? Next, Pintejin Ceramics to introduce to you. Zirconia ceramic machining flow 1. Purchase of raw materials, namely zirconia powder, zirconia powder is a white heavy amorphous powder, odorless, tasteless, soluble in a mixture of 2 parts of sulfuric acid and 1 part of water, slightly soluble in hydrochloric acid and nitric acid, slow Soluble in hydrofluoric acid, almost insoluble in water.It is irritating, the relative density is 5.85. The melting point is Read more

What are the types of special ceramics? What are the new developments in the application of special ceramics? The following will be introduced by Pintejin ceramic manufacturers. Special alumina ceramic plate 1. Classification of special ceramics: According to their application functions, special ceramics can be roughly divided into two categories: high-strength, high-temperature resistant and composite structural ceramics and electrical and electronic functional ceramics. Inorganic materials with special formula are added to the ceramic blanks, which are sintered at a high temperature of about 1360 degrees to obtain stable and reliable anti-static properties and become a new type of special ceramics, which usually have one or more functions, such as: electricity, Read more

With the continuous development of science and technology, precision ceramic plungers have been widely used in medical equipment, environmental engineering, petroleum, chemical and other industries. How do consumers check the quality of precision ceramic plungers when purchasing precision ceramic plungers? Next, Pintejin ceramic manufacturers will explain how to test the quality of precision ceramic plungers. Alumina Ceramic Plunger Precision ceramic plunger is an ideal replacement for similar metal pumps because metal materials are more susceptible to corrosion in use, while precision ceramic plungers are highly resistant to corrosion. In addition, the precision ceramic plunger is produced with modern engineering ceramic materials, so it also has super hard wear resistance, so Read more

Common zirconia toughened ceramics are: zirconia-Mg0, zirconia-alumina, zirconia-Yz 03, zirconia-Ca0. Now developed zirconia-Ce02, Y2 03-zirconia-Hf02 and so on. In addition, there are whisker (fiber)-zirconia composite toughened ceramics. Its toughness is shown in Table 2-1-10. Table 2-1-10 KI c value of several toughened ceramic materials Material Kic (MN . m-3/2) ZrOl-Y203 (pseudotetragonal) 6～9 Zirconia-Ca0 (precipitation strengthening) 9.6 Oxidation Zirconium-Mg0 (precipitation strengthening) 5.7 Zirconia (partially stabilized-stable phase) 1.1 Zirconia-A12 0a 9.8 Sia N4 4.8～5.8 SiC 3.4 B4C 6.0 Alz Oa 4.5 Spinel single crystal 1.3 It can be seen from the above table that the toughened ceramic material has much higher mechanical properties than the previous structural materials such as Sia N4 Read more

In the industrial industry, ceramic parts are constantly developing. Today, Pintejin Ceramics Factory will introduce the advantages of ceramic parts. This kind of ceramic parts is often used in industrial equipment parts. Ceramic tube is a chemical substance with strong covalent bond, and its Si-C bond inorganic compound is only about 12%. Therefore, it also has physical properties, oxidation resistance, high wear resistance and low friction resistance. Industrial ceramic tubes are mainly used in the production and manufacture of power electronic technology industrial production, such as the casing of high-frequency power rectifier tubes, electric vacuum tube power switches, etc. Laminated glass is the raw material of the rectifier tube tube Read more

The superior performance of fine ceramics is of great significance to the improvement of the performance of weapons and equipment. It has become an inevitable trend in the development of weapons and equipment to speed up the application of fine ceramics in weapons and equipment and expand its scope of use. However, the expensive machining cost and low reliability have become the “bottleneck” that restricts the application of fine ceramics in weapons and equipment. Therefore, in order to realize the practical and popularization of ceramics in weapons and equipment, the key is to improve the reliability of the use of ceramics and reduce their machining costs. In order to realize Read more
