Effects of SiC and MgO on aluminabased ceramic foams filters

Blog Article

Alumina-based foam ceramic filters were fabricated by using alumina, SiC, magnesia powder as major materials.It has been found that this ceramic filter has a uniform Dryer Door Catch Spring macrostructure for filtering molten metals.The influences of SiC and magnesia content, the sintering temperatures on ceramic properties were discussed.

Aluminabased foam ceramic filters containing 2.2 mass% magnesia and 7.6 mass% SiC BIOTENE H-24 has a compressive strength of 1.

36 MPa and a thermal shock resistance of 5 times.Its main phases after 1 hour sintering at 1 500 consist of alumina, silicon carbide, spinel and mullite.
