New ceramic materials have their unique advantages in performance and are widely used in the field of modern science. The following Pintejin zirconia ceramic machining manufacturers will introduce the classification and performance of new ceramic materials to you. In terms of thermal and mechanical properties, the new ceramic materials have high temperature resistance, heat insulation, high hardness, wear resistance, etc.; in terms of electrical properties, they have insulation, piezoelectricity, semiconductor properties, magnetic properties, etc.; in terms of chemical properties It has the functions of catalysis, corrosion resistance and adsorption; in terms of biology, it has certain biocompatible properties and can be used as biological structural materials. But it also has Read more

Ceramic materials are typical hard and brittle materials. Before the mid-to-late 20th century, people thought that zirconia ceramic materials could not be processed or could not be processed, so they could only be processed into the desired shape when making green bodies, and then used directly after firing. The reason for removing the hard and brittle characteristics of the ceramic material itself is mainly due to the lack of machining tools and machining methods at that time. Although people have discovered superhard materials such as diamond and vertical boron nitride that are much harder than ceramic materials, the machining of ceramic materials has only been developed in recent decades. The Read more

Performance of zirconia ceramics: pure ZrO2 is white, yellow or gray when it contains impurities, and generally contains HfO2. Zirconia ceramics are a new type of ceramics. Because of their excellent physical and chemical properties, zirconia ceramics have not only become a research hotspot in the field of scientific research, but also have been widely used in industrial production. Zirconia ceramics have the best high-temperature thermal stability and thermal insulation performance, and are suitable for ceramic coatings and high-temperature parts. The thermal conductivity of zirconia ceramics is the lowest among common ceramic materials, and the thermal expansion coefficient is relatively close to metal materials. It is an important structural ceramic Read more

With the development of science and technology, the quality requirements of zirconia toughened alumina products are higher and better, so the products have certain friction during preparation, which is what we call friction theory. The following will introduce the friction theory in detail: 1. Zirconia toughened alumina adhesion theory: The adhesion theory of zirconia toughened alumina believes that under a certain pressure, when zirconia toughened alumina is dry rubbed, it will generate instantaneous high temperature, sometimes even more than 1000e, which will cause zirconia toughened alumina to produce a certain degree of damage. Plastic deformation, the two objects will stick together. Its friction is a pulsating process in which sticking Read more

Special ceramics, also known as fine ceramics, are classified according to their application functions and 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, magnetism, Optical, thermal, acoustic, chemical, biological and other functions; and coupling functions, such as piezoelectric, pyroelectric, electro-optical, acousto-optical, magneto-optical and other functions. At present, special ceramics have been widely Read more
