Characteristics of advanced alumina ceramics and their applications in various industries

In addition to the advantages of high strength, high hardness, corrosion resistance to acid and alkali and high chemical stability, but also has the scraping wear resistance, no signal shielding, excellent heat dissipation performance, good appearance effect; the following by the professional production of advanced alumina ceramic manufacturers to introduce the characteristics of advanced alumina ceramics and application in various industries.

1. Properties of alumina ceramics

Alumina ceramics is a flexible and cheap oxide with a melting point of more than 2,000. Alumina is the most widely used ceramic material and produces greatly in oxide ceramics.

The study shows that there are 12 homogeneous polycrystalline variants of Al2O3, with three main application types: Al2O3, Al2O3 and Al2O3, which have different structures and great differences in properties.

Al2O3 Is a triangular crystal system with compact structure, low chemical activity, high high temperature stability, and excellent electrical and mechanical properties. Al2O3 Is a polyaluminate mineral with high Al2O3 content, whose chemical composition includes a certain amount of alkaline soil metal oxides and alkali metal oxides, and can also exhibit ionic conductivity. Al2O3 Is a spinel-type cubic structure. Unstable at high temperatures and have poor mechanical and electrical properties. However, it has high specific surface area and strong chemical activity, and can be used as an adsorption material after technical improvement.

The application of the alumina ceramics

①. chemical engineering

Al2O3 Ceramics are also widely used in chemical engineering, such as Al2O3 ceramic filled spheres, inorganic microfilter membranes, and corrosion-resistant coatings.

Building / hygiene / ceramic aspects.

In the field of construction and sanitary ceramics, products are seen everywhere, such as Al2O3 ceramic lining tiles, grinding media, rollers, ceramic protective tubes and Al2O3 refractory materials.

②. Electronic / electrical aspects

There are various Al2O3 ceramic substrates, substrate, ceramic membranes, transparent ceramics and Al2O3 ceramic insulators, electronic materials, magnetic materials.

③. Al2O3 Ceramic substrate

Al2O3 Ceramic matrix has high mechanical strength, good insulation, light resistance and other excellent properties. Widely used in multi-layer wiring ceramic substrate, electronic packaging and high-density packaging substrate.

④. Al2O3 Clear ceramics

At present, transparent ceramics is an important frontier of materials research and application in the field. As a new material, transparent ceramics has a wide range of light transmittance, but also has a series of advantages of high thermal conductivity, low electrical conductivity, high hardness, high strength, low dielectric constant and dielectric loss, good wear resistance and high temperature resistance and so on. Corrosion resistance.

Other Al2O3 are one of the new materials for current research and applications. In addition to the above applications, it is also widely used in other high-tech fields, such as aerospace, high-temperature industrial furnaces, composite reinforced materials, etc.
