Document Type and Number:
Japanese Patent JP4324258
Kind Code:
B2
Abstract:
An alkaline silicate suspension is reacted with an aqueous solution of a zinc salt at normal pressure and at temperatures between 50 degrees C and the boiling point of the suspension arising. It is alternatively reacted under hydrothermal conditions at the suspension boiling point up to 250 degrees C. Aqueous pH value is held at 4-9.5 throughout. The Zn/Si atom ratio is kept within 1.6-2.5. Preferred Features: From the product, a suitable zinc silicate, is formed. This has the hemimorphite structure as claimed, the composition Zn4Si2O7(OH)2-2yOy.xH2O, where x and y are between 0 and 1. To this end the product is roasted at temperatures of 70-600 degrees C. pH is maintained in the region 5.5-8 or 6-7.5. When reactin other salts, 0-20 mol% of the following group A, referred to zinc, is used with 0-20 mol% of the following group B, referred to silicon, (i.e. the elements in the hemimorphite structure described). Group A comprises: beryllium, magnesium, calcium, strontiu barium, manganese, iron, cobalt, nickel, copper, cadmium and mercury. Group B comprises: titanium, zirconium, hafnium, germanium tin and lead
