Abstract

1,050,275. Making activated clay. DAINIPPON INK & CHEMICALS Inc. Feb. 19, 1964 [March 5, 1963], No. 7009/64. Heading C1A. [Also in Division C3] Activated clay is produced by drying natural acid clay at ambient temperature, powdering it, and then heating at above 90‹ C. under at least atmospheric pressure with dilute acid, filtering, washing and drying at 120-200‹ C.
