High Alumina Porous Products

For most of the ceramic manufacturers, a pore is a flaw that has to be avoided. Very few of them can incorporate pores with predefined properties in ceramic materials. CeramTec designs and manufactures ceramic products with variable porosity and pore sizes for versatile applications. Each material offers a unique set of advantages that pay off in the respective application.


High purity alumina ceramic pots also known as P80 oxamat or diaphragma cells have established themselves as standard material for chrome plating process. Due to its excellent chemical resistance it can withstand even aggressive chromicsulfuric acid. As sulfuric acid is used in electroplating, plant operators need a resistant ceramic that must allow chromium ions to pass through. Metallic impurities can be prevented with the aid of such a permeable medium.

Electrochemical industry

As of high mechanical and chemical resistance, diaphragma plates are also used in electro chemical process where electrical energy is converted to produce the chemicals. These discs allow only certain ions to pass from anode to cathode. The effect is reverse of a battery, where chemicals are converted into electrical energy.

Agricultural sector

Our P80 ceramic is the most suited material for tensiometer cups, soil moisture level measuring instrument. The tensiometer cups made by CeramTec make it possible for agriculturist to grow the plants using high technology by understanding irrigation demands.


Cross-flow filtration is a filtration process in which a suspension is pumped through porous tubes, so-called membranes, and the filtered liquid, the permeate, is drawn off transversely to the direction of flow. Ceramic membrane carriers score points with their high mechanical, chemical and thermal resistance, among other things.
