143 results about "Calcium pyrophosphate" patented technology

Calcium pyrophosphate (Ca₂P₂O₇) is a chemical compound, an insoluble calcium salt containing the pyrophosphate anion. There are a number of forms reported: an anhydrous form, a dihydrate, Ca₂P₂O₇·2H₂O and a tetrahydrate, Ca₂P₂O₇·4H₂O. Deposition of dihydrate crystals in cartilage are responsible for the severe joint pain in cases of calcium pyrophosphate deposition disease (pseudo gout) whose symptoms are similar to those of gout. Ca₂P₂O₇ is commonly used as a mild abrasive agent in toothpastes, because of its insolubility and nonreactivity toward fluoride.

Process for preparing modified ardealite by water-free calcining

The invention relates to a method for preparing modified phosphogypsum through calcination without water scrubbing. The method is as follows: firstly, composite excitant and modifier are added into phosphogypsum and uniformly mixed, wherein, the weight percent of the phosphogypsum is between 85 and 95 percent; the weight percent of the composite excitant is between 2 and 5 percent; the weight percent of the modifier is between 3 and 10 percent; the composite excitant is green vitriol and aluminum sulphate, and the modifier is calcium oxide and cement; secondly, after uniform mixing, the mixture is dried at a drying temperature of between 100 and 110 DEG C, and the moisture of the phosphogypsum is lower than 8 percent; thirdly, the mixture enters into a calciner, is calcined for 0.5 to 1 hour at a temperature of between 150 and 300 DEG C, and is naturally cooled to prepare the modified phosphogypsum. The method decomposes and volatilizes harmful substances such as phosphor, fluorine, organic substances and so on contained in the phosphogypsum or converts the harmful substances into inert substance calcium pyrophosphate which is harmless to products, thereby not only avoiding secondary pollution but also reducing or avoiding influence of harmful chemical microconstituents contained in the phosphogypsum on the quality and the performance of the products. Moreover, the method shortens the processing time by 15 to 20 percent, saves the investment by 3 to 8 percent and reduces the energy consumption by 10 to 20 percent.
