AdTech provides a filter for molten aluminum, which has high thermal shock resistance, high corrosion resistance, adequate strength, is economical to produce, is environmentally friendlier and has a low density.<\/p>\n

A particular feature of ceramic foam filters is the ability to utilize relatively inexpensive starting materials while still achieving superior performance. AdTech specially designed Ceramic Foam Filters are made of the basic raw material Aluminium Oxide, which is also called \u0645\u0631\u0634\u062d \u0631\u063a\u0648\u064a \u0645\u0646 \u0633\u064a\u0631\u0627\u0645\u064a\u0643 \u0627\u0644\u0623\u0644\u0648\u0645\u064a\u0646\u0627<\/a>.<\/p>\n

Alumina ceramic foam filter for molten aluminum alloys comprising an alumina-silicate rich core and a boron glass shell and a chemical composition comprising: 20-70 wt % Al2O3, 20-60 wt % SiO2, 0-25 wt % of at least one oxide and 2-20 wt % B2O3.<\/p>\n

Yet another embodiment is provided in a process for forming a ceramic foam filter. The process includes forming a slurry comprising a solid phase comprising 20-70 wt % alumina, 20-60 wt % silica, 0-20 wt % calcium compound, 0-20 wt %; magnesia and 2-20 wt % boron compound and a carrier phase. Impregnating an open-cell foam with the slurry, volatilizing the carrier, and sintering.<\/p>\n

A particularly preferred embodiment is provided in a ceramic foam filter comprising 65-85 wt % of a core and 15-35 wt % of a shell encasing the core wherein the core comprises alumina silicate and wherein the shell comprises 15-45 wt % alumina, 2-35 wt % silica, 15-50 wt % boron oxide and 0-25 wt % of at least one oxide preferably calcium, barium, magnesium or strontium.<\/p>\n
