Porous alumina ceramics have excellent heat resistance, high hardness and excellent chemical stability. It is an ideal catalyst carrier. It uses catalytic combustion to convert organic waste gas into non-toxic carbon dioxide and water.


Industrial Ceramic


Porous alumina ceramics can be used as humidity sensors. Its working principle is that water in the air is adsorbed on the porous surface, causing changes in the conductance of the material. That is, the greater the air humidity, the thicker the water layer adsorbed by the porous alumina ceramics. , The greater the conductivity of the sensor, so the humidity of the surrounding environment can be inferred based on the conductivity of the material.

RFQ

Is alumina ceramic porous?

This ceramic technology provides a broad spectrum of chemical compatibilities and robustness in high temperature and pressure scenarios. High purity porous ceramics, especially porous alumina (or aluminum oxide Al2O3), are recognized for their mechanical strength, wear resistance, and resilience in corrosive settings.

Can alumina ceramic be machined?

Once fired and sintered, it can only be machined using diamond grinding methods. Advanced green and biscuit machining techniques developed by allow more complex components to be manufactured using traditional machining methods.
