The difference between precision alumina ceramic sheets and ordinary ceramic sheets and 95 alumina precision ceramics

Precision alumina ceramic sheets are also called precision alumina ceramic linings, high-aluminum linings, precision alumina ceramic patches, precision alumina linings, etc. So what is the difference between it and ordinary ceramics? The following is introduced to you by the Swiss Industrial Technician.

Precision alumina ceramic sheet

Precision alumina ceramic sheet features: First of all, the hardness is high, its Rockwell hardness can reach HRA80-90; its wear resistance is excellent, wear resistance can be higher than manganese steel and high chromium cast iron, can extend the service life of equipment More than double; the precision alumina ceramic sheet is very light, its density is 3.65g/cm, which can greatly reduce the load of the equipment; the precision alumina ceramic sheet is firmly bonded on the equipment and has good heat resistance. Long-term operation at 350 ° C does not age.

What is the difference between precision alumina ceramics and ordinary ceramics?

Why does a precision alumina ceramic piece have such a name? In fact, it is very simple, that is, in the ordinary ceramic piece composition, additional precision alumina components are added, so in the name, this is especially The name of the ingredient is marked to give people a good understanding of the difference between the precision alumina ceramic piece and the ordinary ceramic, so that the properties of these different ceramic materials can be better understood. People can help a lot, so that when you use these different materials, you can distinguish them more effectively.

Why do you add the aluminum oxide component to the ceramic piece? What is the difference between such a precision alumina ceramic piece and ordinary ceramics, and what are the different performances? With the addition of such precision alumina components, the hardness of the ceramic sheets has been greatly improved. In particular, such precision alumina ceramic sheets are currently the most lubricious material, so in the production of many industrial equipment. It has become the best and most practical material, and it has now been fully applied.

Precision alumina ceramic sheet

The most critical point is that compared with ordinary ceramic sheets, precision alumina ceramic sheets are very different in composition and manufacturing process. Ordinary ceramics are made through raw material preparation, billet forming and kiln firing. In the process, most of the precision alumina ceramic sheets are manufactured by the powder sintering technique.

95 alumina precision ceramics, is a kind of alumina precision ceramics. According to the content of alumina in the product, it can be classified into 99 alumina, 95 alumina, and the like. Below is the introduction of 95 alumina precision ceramics by Kezhong Precision Ceramics.

95 alumina precision ceramic skeleton

Alumina precision ceramics are classified into 75 porcelain (75%), 92 porcelain (92%), 95 porcelain (95%), 96 porcelain (96%), 97 porcelain (97%), 99 porcelain (99%), and 995 porcelain (99.5%) and 997 porcelain (99.7%).

At present, most domestic manufacturers produce 95% alumina precision ceramic products, and the current products have a tendency to develop at high levels.

95 alumina precision ceramics is based on alumina, with good chemical resistance and molten metal, high temperature resistance, good finish, thermal stability, small thermal expansion coefficient, good thermal conductivity, high mechanical strength, and insulation. High strength, hardness is the same as corundum, and wear resistance is comparable to super hard alloy.

It can be used for bio-precision ceramics, electronic components such as high-voltage switch shell insulation materials, mechanical parts such as seal ring valve parts, wear-resistant materials such as wear-resistant precision ceramic balls and rods, high-temperature devices such as high-temperature liquid delivery tubes.

Ultrasound is required for washing. Superior performance, more and more applications, to meet the needs of daily use and special performance.

95 alumina precision ceramic parts

Widely used in lighting electrical appliances, electric heating appliances, petrochemicals, machinery, textiles, automobiles and other industries, the specifications can be customized according to customer needs.

However, 95 alumina ceramics are mainly used as corrosion-resistant and wear-resistant parts. In addition, 95 alumina precision ceramic materials perform well. In terms of mechanical properties, mechanical properties refer to the ability of a material to resist without mechanical damage. Generally, the tensile strength, the flexural strength and the compressive strength are divided according to the direction of the force, the direction of the force and the point of stress.

The tensile strength of 95 alumina precision ceramics is generally above 160 MPa and is usually greater than the best sealing strength.
