O.V. Roman Powder Metallurgy Institute offers consumers ceramic foam filters for purification of metal melts under a manufacturing agreement or the transfer of manufacturing technology under a license agreement and is looking for partners to conclude a distribution services agreement.

The production of ceramic foam filters for purification of metal melts has been mastered at the O.V. Roman Powder Metallurgy Institute.

Cellular ceramic foam has an arch-labyrinth pore structure, consisting of a system of interconnected cells.

Feature of cellular ceramic foam - extremely high porosity and permeability, high structural rigidity, low density.

Possible compositions of ceramic foam: mullite-corundum, corundum, zirconium dioxide.

The main characteristics of the material:
* Open porosity - 75..85%;
* Bending strength - 1..5 MPa;
* Maximum operating temperature - 1 550 ºС;
* Average pore size - 1..5 mm;
* Viscosity coefficient of permeability - 10e-9..10e-8 m2;
* The maximum linear size - 180 mm;
* Thickness - 10..25 mm.

Technologies for producing cellular ceramic foam filters for cleaning have been developed:
- Aluminum and its alloys
Metal pouring temperature up to 900ºС.

- Gray and ductile iron.
Metal pouring temperature up to 1500ºС.

- Heat-resistant alloys and steels.
Metal pouring temperature up to 1700ºС.

The effectiveness of the use of cellular ceramic foam filters:
Foundry marriage (sand and slag inclusions, pores) of gray cast iron castings when casting in raw sand-clay molds is 14-20%. After using cellular ceramic foam filters with a pore size of 2-3 mm, the level of casting rejects is reduced to 3-4%.

Patent rights are protected in the CIS countries.
