摘要

"Processes for production of hexaborato tetrahydrate crystals and calcium for the dehydration of the composition of calcium hexaborato tetrahydrate crystals.Hexaborato tetrahydrate crystals of calcium, and composition of hexaborato amorphous calcium ".An improved process is provided for the production of calcium hexaborato tetrahydrate crystals, nobleu00edta synthetically, through the reaction of boric acid and lime in an aqueous slurry.The reaction conditions including molar relations of boric acid to water greater than 0.25, 1, molar relations of lime for the boric acid in the range 0.05 - 0.15: 1 and temperatures in the range of 60 - 85 u00b0 c. a concentration of at least 25% by weight of solids dissolved in the aqueous slurry of the product.
