RFQ

What is alumina ceramic used for?

Other essential applications of alumina ceramics can be seen in seal rings, medical prostheses, laser tubes, thermocouple tubes, electronic substrates, ballistic armor, electrical insulators, grinding media, and wear components.

Why is alumina expensive?

It is expensive, largely because of the amount of electricity required in the extraction process. Aluminium ore is called bauxite close bauxiteA rock that can be used to make aluminium.. The bauxite is purified to produce aluminium oxide, a white powder from which aluminium can be extracted.

How long does alumina last?

Material: Activated alumina, molecular sieve, life is different according to the temperature of the intake air, 2-6 years, according to the filter after the dryer to determine whether a desiccant is needed. If the filter is drained, it needs to be replaced immediately.
