Abstract

Luminous or phosphorescent powders are formed by heating a mixture of strontium, calcium and magnesium carbonates so as to form the oxides, adding lithium and rubidium carbonates, aluminium silicate, a carbonaceous substance such as starch, sulphur, a small quantity of soluble metallic salts which serve to impart phosphorescence (termed phosphorogens) and a small quantity of metallic salts which serve as a flux (termed luminophores). The mixture is heated in a non-oxidizing furnace at 500-1300 DEG C. for 30-90 minutes, cooled, ground and reheated in a current of hydrogen. As phosphorogens, thorium, bismuth, thallium, erbium, rubidium, nickel and silver nitrates or mixtures may be used, and they may be introduced in the form of alcoholic solutions. As luminophores, which are stated to distribute the phosphorogen throughout the base, are employed sodium chloride, sulphate, fluoride, carbonate, or hyposulphite, potassium chloride, sulphate or bi-chromate, manganese chloride or sulphate, calcium fluoride, barium sulphate, or rubidium sulphate or mixtures. The luminous powder may be mixed with resins or cellulose derivatives and solvents or linseed oil and turpentine containing zinc sulphide, barium sulphate, zinc sulphate and calcium carbonate to form paints. Specification 245,612 [Class 95, Paints &c.], is referred to.
