At present, the main raw material for the production of special alumina products is industrial alumina, which is an intermediate product of the aluminum smelting industry. Its true density is 3.60g·cm-3, and its mineral composition is γ-Al2O3. Industrial alumina is white powdery material. The chemical composition of general products is shown in the table. When manufacturing special pure products, raw materials with Al2O3 content greater than 99.8% or raw materials prepared from aluminum sulfate and ammonium sulfate should be used. Industrial alumina is difficult to sinter. In order to improve the sintering temperature, the raw materials need to be finely pulverized and pre-sintered, and additives that promote sintering are added. Read more

In the realm of modern electronics, where precision and efficiency reign supreme, the quest for superior materials and manufacturing techniques is unending. Among the myriad of components that constitute the backbone of electronic devices, printed circuit boards (PCBs) stand as fundamental pillars. These intricate platforms serve as the very foundation upon which electronic circuits are built, enabling the seamless flow of electrical signals. In this pursuit of excellence, one innovation has emerged as a cornerstone in the domain of PCB fabrication: the Alumina Multi-Layered Board by Etching. The Alumina Multi-Layered Board (AMLB) represents a pinnacle of engineering ingenuity, combining the remarkable properties of alumina with the intricacy of multi-layered design. 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

What industries are ceramic parts generally used in? Our ceramic parts can be divided into ordinary ceramic parts and precision ceramic parts.

In recent years, my country’s industrial ceramics have developed rapidly, and it has become a large cross-industry and interdisciplinary industry. The output value of the national industrial ceramics has accounted for more than half of the ceramic industry, and it has a very important strategic position in the entire national economy. Experts predict that the market demand for industrial ceramic products in China will grow at an average annual rate of about 8.5%. Industrial ceramic technology is an important part of the application field of science and technology. Most high-tech development is inseparable from high-tech industrial ceramics, and the development of high-tech industrial ceramics also requires high-tech support. Facing the 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

The production of ceramic products has a long history in China. After a long period of development, the manufacturing process has been continuously developed. Especially in the past two decades, the reasonable adjustment of the structure of zirconia ceramic products has catered to the consumer demand of consumers at home and abroad, and with the development of society and the improvement of living standards, the application range in life has become wider and wider. At the same time, my country’s total export trade of ceramic products is making every effort to increase. The export of daily-use ceramics, architectural ceramics, sanitary ceramics and zirconia ceramics has shown a gratifying scene of 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

The sintering temperature of zirconia ceramics is very high when the recrystallized silicon carbide setter is used for production. high; The working temperature of the recrystallized silicon carbide setter plate can reach 1650 ℃; the thermal shock resistance is excellent and the best setter plate; but because the main component of the silicon carbide setter plate is SIC+SIO2; Among them, the SIO2 in the recrystallized silicon carbide setter plate cannot be completely obtained from the group, so some SIO2 still exists in the form of crystalline; Due to the relatively high activity of SIO2, when SIO2 encounters all substances that can be combined at high temperature, it will immediately combine Read more

To study the influence of porosity on thermal properties such as thermal conductivity of ceramic materials, it is necessary to prepare a series of samples. Porosity is the only main variable parameter in the product. This requires: the zirconia and alumina ceramic raw materials used between the samples are the same; the shape, size, orientation and other factors of the pores are roughly the same. It should be admitted that it is quite difficult to control the shape and size of the pores in the sample. Start from an angle, such as: Control the particle size of the added organic matter. Pass the organic matter (naphthalene powder) through two different Read more
