Abstract
A means for promoting the neutralization reaction between particulate calcium carbonate and ionized phosphate by adding a material formed by the reaction of particulate calcium carbonate and dilute hydrofluoric acid. The products of this invention are useful in lowering serum phosphate levels in patients undergoing renal dialysis, and are also useful as antacids. These products are also useful in the treatment of water and waste water to lower phosphate content.
