What is the difference between microporous ceramics and zirconia ceramics?

Recently, many users consult microporous ceramic products, here to briefly give you a science, we look at microporous ceramics and zirconia ceramics what exactly the difference.

Different structure

Microporous ceramics refers to the ceramic body containing a large number of open or closed tiny pores inside or on the surface of the ceramic, its pore size is generally micron or sub-micron level.

Zirconia ceramics is a material with a high resistance to crack expansion. It has a high coefficient of thermal expansion and is therefore often used in the production of metallised ceramics.

Different properties

Microporous ceramics are functional structural ceramics. Microporous ceramics are adsorptive, permeable, corrosion resistant, environmentally compatible and biocompatible.

Zirconia ceramics are dense, hard and have a water absorption rate of 0. Zirconia is an extremely dense ceramic material. It has both low thermal conductivity and high strength, two outstanding properties.

Different applications

Microporous ceramics are widely used for filtration of various liquids, filtration of gases and for fixing biological enzyme carriers and bio-adaptive carriers, especially for a large number of applications in environmental engineering, such as the treatment of industrial and domestic water and the purification of sewage. Microporous ceramics can be used in oilfield oil extraction operations, filtration of acid and alkaline solutions in chemical plants, filtration of various beverages, beer, fermentation and the sugar industry, which can greatly improve the quality of products in these industries.

Zirconia ceramics can be used as moulds for wire forming, can be used as an auxiliary material in welding processes and are often a good choice for insulating rings in high temperature environments. Common applications include laser parts, mechanical components, fibre optic ceramic rings and sleeves, semiconductor top teeth and many more.

Alumina ceramics are a very wear resistant precision ceramic material and are used in a wide range of industries. The main forming methods for alumina ceramic products are: dry pressing, isostatic pressing, injection moulding and calendering. Different forming methods are required for different product shapes, sizes, complex shapes and precision. Alumina ceramic products that have been sintered at high temperatures can only be processed using the diamond grinding process. Alumina ceramic materials are extremely hard and wear resistant, highly resistant to corrosion, high temperatures, corrosion resistant and biologically inert. In addition, the high temperature sintered alumina can be highly polished and is used in many applications.

The insulation strength of alumina ceramics is much higher than that of other oxide ceramics and there is a relationship between the insulation strength of alumina ceramics and its purity. The higher the purity of the alumina, the higher its insulating properties and, of course, the higher the price.

Alumina ceramics with wear resistance, high level of resistance, high strength and high insulation properties are widely used in high-end fields such as instrumentation, food and medical, solar photovoltaic, machinery and electrical appliances, laser and semiconductor, petroleum machinery, automotive and military, aerospace and other high-end fields. Common products include ceramic insulating rings, ceramic insulating sheets, ceramic substrates, ceramic arms, ceramic plungers, ceramic dispensing valves, etc.
