SILICATES BASED ON ALKALINE TERRAE, COPPER AND EVENTUALLY TITANIUM, BLUE OR VIOLET PIGMENTS BASED ON THESE SILICATES, THEIR PREPARATION PROCEDURE AND THEIR USE.

摘要

THE INVENTION REFERS TO SILICATES BASED ON ALKALINE TERRAIN ELEMENTS AND COPPER AND EVENTUALLY TITANIUM, CHARACTERIZED BY THEY ARE PRESENTED IN THE FORM OF AGGLOMERATES WELL CONSTITUTED BY LARGE MONOCRISTALINE THEMSELVES, THEMSELVED BY THEMSELVES. THESE SILICATES ARE PREPARED BY A PROCESS CHARACTERIZED BY WHICH IT INCLUDES THE FOLLOWING STAGES: A SUN OF SILICE OR A SILICATE AND EVENTUALLY A TITANIUM SUN IS MIXED WITH SALTS OF THE OTHER CONSTITUTIVE ELEMENTS OF SILICATE WITH THE EXCEPTION OF OXYGEN; THE MIXTURE SO OBTAINED IS DRIED, PREFERENTLY BY ATOMIZATION AND THE PRODUCT OBTAINED IS CALCULATED. SILICATES OF THE INVENTION MAY BE USED AS COLORED PIGMENTS IN PLASTIC MATERIALS, PAINTINGS, SURFACE COATINGS, RUBBER, CERAMICS, GLASSES, PAPERS, INKS, COSMETIC PRODUCTS, DYES AND COATINGS.
