CHARGE FOR PREPARING OF CALCIUM-TUNGSTEN ROENTGEN-LUMINOPHORE Russian patent published in 1995 - IPC

Abstract RU 2034898 C1

FIELD: chemical technology. SUBSTANCE: charge has the following components, wt.-%: calcium chloride 0.5-6; magnesium chloride hexahydrate (as anhydrous salt) 0.1-5, and purified calcium tungstate - the rest. Demineralized water, solution CaCl₂ and solution MgCl₂ were added to purified calcium tungstate, prepared charge is dried up to dusting state and calcined in air at 900 C for 1 h. Luminophore properties: relative intensity is 102-132%; relative post-luminescence is 14-99%; mean particle size is 3.8-5.0 mcm. EFFECT: enhanced quality of luminophore. 1 tbl
