A ceramic foam filter and method of making the filter is described. The filter comprises: a sintered reaction product of: 35-75 wt% aluminosilicate; 10-30 wt% colloidal silica; 0-2 wt% bentonite; and 0-35 wt% fused silica; wherein the ceramic foam filter has less than 0.15 wt% alkali metals measured as the oxide and a flexural strength of at least 60 psi measured at 4 minutes at 1428°C.
