A method of producing a porous inorganic particulate material which comprises treating a particulate aluminosilicate material with a leaching agent which chemically reacts with or solubilises aluminium and thereby leaches aluminium from the aluminosilicate material, wherein the particulate aluminosilicate material is a particulate hydrous aluminosilicate material which has been flash calcined.
