    • An aqueous slurry according to the invention comprises (a) a crystalline aluminosilicate represented by the empirical formula M 2/n O Al 2 O 3 .xSiO 2 .yH 2 O wherein M represents a first metal moiety, said first metal having a valency of n, x indicates the ratio of atoms of silicon to atoms of aluminium and y indicates the ratio of molecules of water to atoms of aluminium, (b) a salt of a second metal selected from the group consisting of Group III metals, metallic elements of Group IV, magnesium, titanium, chromium, iron, nickel, copper, zinc, zirconium and silver, said salt of a second metal being present in an amount which is sufficient to replace from about 2.0 to about 40 per cent by weight of the first metal moiety, and (c) particulate silica having a BET surface area greater than 500 m 2 /g and a pore volume, as measured by nitrogen manometry of less than 2.1 cm 3 /g. The slurry is stable on storage but has a low viscosity at low shear rate.
    • 根据本发明的含水浆料包含(a)由经验式M2 / nO Al 2 O 3·xSiO 2·yH 2 O 2表示的结晶硅铝酸盐,其中M表示第一金属部分,所述第一金属具有n价,x表示原子比 的硅原子与y表示水分子与铝原子的比例,(b)选自第III族金属,第IV族金属元素,镁,钛,铬的第二种金属的盐 ,铁,镍,铜,锌,锆和银,所述第二金属的盐的存在量足以代替第一金属部分的约2.0至约40重量%,和(c)颗粒 BET表面积大于500m 2 / g的二氧化硅和小于2.1cm 3 / g的氮压力测量的孔体积。 浆料在储存时稳定,但在低剪切速率下具有低粘度。
