Classification, properties, advantages and disadvantages of alumina ceramics

Alumina ceramics can be divided into two types: high-purity type and common type.

Material composition and selection of high-temperature kiln furniture

High-temperature kiln furniture is mainly made of corundum mullite, with 80% alumina content and about 20% silicon oxide content, density of 2700-3000 kg/m3, pure white color, no pollution caused by any impurities, imported raw materials, long-term service temperature up to 1700+degrees, all inspected according to Japanese standards

What are the categories of industrial ceramics?

Ordinary ceramics refer to clay ceramics, which are fired from clay, feldspar and quartz in proportion. Its performance depends on the purity, particle size and proportion of the three raw materials. Generally, it is hard, corrosion-resistant, non-oxidizing, non-conductive, able to withstand certain high temperatures and has good processing formability.

Which refractory material is used for the construction of complex parts of kiln lining

The construction of complex parts of high-temperature kiln equipment can be selected according to the actual situation. If it is impossible to support the mold, fire-resistant coating materials, wear-resistant plastic materials, etc. can be used. If it is impossible to vibrate, wear-resistant self-flow castables can be used.

Specific differences between alumina ceramic rod and zirconia ceramic rod

Ceramic rods, also known as ceramic round rods, are mainly formed, sintered and processed from zirconia and alumina ceramic raw materials. The market demand for ceramic rods is very large, and they have been widely used in military, aerospace, industrial and other fields. Different industries have different demands for ceramic rods. The main factors to consider are: wear resistance, thermal insulation, high temperature resistance, corrosion resistance, lubrication and other functions of ceramic rods!
