Alumina ceramics have the advantages of high impact toughness, good dielectric strength, low high frequency loss, high electrical and compressive strength, heat resistance, heat shock resistance, etc., and have the unmatched advantages of glass. It is suitable for high power on the market. Electron tube.

The forming methods of alumina ceramic tubes include dry stamping, slurry injection, stamping, cold isostatic pressing, hot pressing, and many other methods. Alumina ceramic tubes require different forming methods according to different shapes, sizes, complex shapes and precision.

Alumina ceramics are calcined at high temperature to obtain alumina ceramics, and the particle size value generally refers to the particle size of the alumina ceramic body. The original crystal particle size and particle size of alumina ceramics are two different terms. In recent years, some colleges and universities and research units have done some research on their own in order to determine the essentials. Of course, there are related reports, but the technical details have not been disclosed. So what are the methods for determining the original grain size of alumina ceramics?

Alumina ceramic structural parts are a product with a very wide range of uses. However, in the actual appointment process, the alumina ceramic structural parts will inevitably be worn. There are many factors that cause structural parts to wear. These can be effectively prevented from these aspects. Wear of alumina ceramic structural parts.

Alumina ceramics is a ceramic material with alumina (Al2O3) as the main body, used for thick film integrated circuits. Alumina ceramics have good conductivity, mechanical strength and high temperature resistance. It should be noted that ultrasonic cleaning is required. Alumina ceramics is a kind of ceramics with a wide range of uses. Because of its superior performance, it has become more and more widely used in modern society to meet the needs of daily use and special performance.

The alumina ceramic​ lining board above 99 is the best among the ceramic lining boards, and the unit price is extremely high, but its physical properties are also excellent, with high hardness and good toughness. It is especially suitable for parts with severe impact and wear.

Alumina ceramic cylinder, alumina ceramic gasket, 95 alumina ceramic base, 99 alumina ceramic insulating tube, 99 or more alumina ceramic insulating tube, ceramic injection molding parts, alumina ceramic discs, ceramic parts, alumina ceramics Plate punching, alumina ceramic parts blind hole addition, alumina ceramic disc grooving, alumina ceramics above 99 are heated up and down, alumina positioning seat, alumina ceramic ring, 99 alumina ceramic coil frame, alumina ceramic circle Disc.

As a widely used material in ceramics, alumina ceramics presents the following development trends along with the development of the entire industry: (1) The level of technical equipment will be rapidly improved: the development of computer technology and digital control technology has promoted the technological progress and rapid development of the ceramic material industry, such as automatic control of continuous sintering kilns, high-power and large-capacity grinding equipment, and high-performance powder manufacturing Complete sets of equipment such as granular equipment and other net pressure forming equipment have beneficially promoted the improvement of the overall level of the industry, and at the same time, the production efficiency and product quality have also been significantly improved;

Alumina ceramics is an industrial ceramic with high hardness, which can only be processed by diamond grinding. It is made of bauxite and can be processed by injection molding, pressing, isostatic pressing, sliding castings and other methods.

High temperature resistance: Alumina ceramics can be used in the atmosphere up to 1650°C or 2900°F, and in the vacuum environment of 2000°C or 3600°F. At 1000 degrees Celsius, it maintains 50% of its tensile strength at room temperature. Although the strength of metals is weakened in high temperature environments, alumina ceramics retain their strength when they return to normal temperatures and remain unchanged. Alumina ceramics have high electrical resistivity and can reduce thermal shock, and increased purity will increase their electrical resistivity. Alumina ceramics become a perfect insulating material due to its dielectric level, etc., and current cannot pass through them.
