1,167,225. Sintered cermets. TEXAS INSTRUMENTS Inc. Feb. 24, 1967 [March 4, 1966], No.8875/67. Heading C7D. [Also in Division H1] ] A sintered cermet is made from a powder mixture comprising by weight 80-98% Al and 20-2% aluminium silicate which is compacted at 10, 000 p. s. i. and sintered at 1000‹-1400‹C. for 4 to 8 hours in an oxidizing atmosphere. The powder mixture may alternatively be hot pressed. The aluminium silicate used is kaolin Al 2 O 3 (SiO 2 ) 2 À2H 2 O or Al 6 Si 2 O 13 or Al 2 SiO 5 and the sintered cermet may be used as a spacing member in a fuel cell using molten LiNaCO 3 as an electrolyte. |
