Abstract: Disclosed is a stable gel-like slurry having a pH of about 6.5 to about 8.5 which is a mixture of water and about 20 to about 50 wt % sodium cyanurate. Also disclosed is a method of making a water-monosodium cyanurate hydrate gel-like slurry. A slurry is formed in water of about 20 to about 50 wt % cyanuric acid. Sodium hydroxide is added to the slurry in an amount of about 90 to about 100% of stoichiometric over a period of about 40 minutes. Water can be disinfected by adding to the water an amount of water-monosodium cyanuric hydrate gel-like slurry according to this invention equivalent to a concentration of cyanuric acid in the water of about 25 to about 150 ppm and an amount of a source of chlorine sufficient to maintain a concentration of chlorine in the water between about 0.1 and about 5.0 ppm.

Abstract: Crystalline calcium sodium metaphosphate is prepared by (a) forming a wet mix slurry having a composition on a dry basis equivalent to a CaO/Na.sub.2 O/P.sub.2 O.sub.5 mol percent ratio of about 24.0-34.0/12.0-18.0/50.0-60.0, with the proviso that the CaO/Na.sub.2 O mol ratio is from about 1.60 to about 2.00, (b) forming and growing product crystals of calcium sodium metaphosphate under crystal formation and growth conditions between the solid phase of the wet mix slurry and substrate crystals of calcium sodium metaphosphate.

Abstract: Substantially crystalline calcium sodium metaphosphate having a degree of crystallinity from about 60% to about 75% as determined from density and differential thermal analysis measurements is prepared by (a) bringing together in water source materials for CaO, Na.sub.2 O, and P.sub.2 O.sub.5 in proportions sufficient to provide a CaO/Na.sub.2 O/P.sub.2 O.sub.5 mol percent ratio on a dry basis of about 29.0-34.0/16.0-18.0/50.0-53.0 and form a wet mix slurry containing a solid phase and an aqueous liquid phase and (b) heating the wet mix slurry at a temperature and for a time sufficient to remove the aqueous liquid phase and calcine the resulting solid phase to form the substantially crystalline calcium sodium metaphosphate.

Abstract: Asbestiform crystalline calcium sodium metaphosphate fiber is prepared by (a) forming a wet mix slurry having a composition on a dry basis equivalent to a CaO/Na.sub.2 O/P.sub.2 O.sub.5 mol percent ratio of about 24.0-34.0/12.0-18.0/50.0-60.0, with the proviso that the CaO/Na.sub.2 O mol ratio is from about 1.60 to about 2.00, (b) forming and growing product crystals of calcium sodium metaphosphate under crystal formation and growth conditions between the solid phase of the wet mix slurry and substrate crystals of calcium sodium metaphosphate, and (c) fiberizing the product crystals of calcium sodium metaphosphate.
