Studies were carried out to develop cordierite kiln furniture of high hot strength with a view to get longer life. Selection of raw materials was based on lowest possible iron impurities. Three different bonds were prepared by mixing talc, China clay and calcined alumina in different proportions. 50% of each bond was mixed with 50% of clay grog to obtain three oxide compositions of 11%MgO.37%Al(2)O(3).48%SiO(2) (N-1), 8%MgO.39%Al(2)O(3).48%SiO(2) (N-2) and 5%MgO.37%Al(2)O(3).50%SiO(2) (N-3). Test bars were fired at 1250 degrees, 1300 degrees and 1360 degrees C for 2 h soaking time. The decrease in MgO from 11 to 8% gave highest hot MOR (105 and lowest thermal expansion (3.0 x 10(-6)/degrees C) due to better formation of cordierite and mullite phases.
