Calcium silicate-phosphates can be prepared by the following procedure. Monocalcium orthophosphate, Ca(H2P04)2, is, according to the method of Hill and Hendricks (38), recrystallized from a 50% solution of orthophosphoric acid. The crystals are then washed with acetone to remove orthophosphoric acid and dried at 70°C. By melting the resulting pure monocalcium orthophosphate at 980-1000°C., calcium metaphosphate is produced. A mixture of the calcium metaphosphate and an appropriate amount of silica gel is melted in a platinum crucible and cooled to form a glass, which has a Ca0/P205 ratio of... [Pg.195]

Monobasic calcium phosphate, Ca(H2P04)2, is also known as calcium hypophosphite, calcium biphosphate, acid calcium phosphate, monocalcium orthophosphate, and primary calcium phosphate. It usually exists in the form of the hydrate Ca(H2P04)2-H20. It decomposes when heated to 2oo°C (400°F)... [Pg.155]

Rather than treating phosphate ore with sulfuric acid as was done for many years to make Super Phosphate fertilizers. Triple Super Phosphate fertilizer is made by treating phosphate ore with green phosphoric acid. The fertilizer is a crude form of monocalcium orthophosphate, Ca(H2P04)2. An added value of this product is a larger quantity of phosphate contained in a pound of fertilizer and its availability by being highly soluble when it is first applied. As time passes it too becomes insolubilized as mentioned above. All phosphates remain soluble and available as nutrients for a short time on farms or in aquatic environments. [Pg.46]

To make life simpler, what one actually does in the laboratory is to heat monocalcium orthophosphate to drive out water contained in the melt and then slowly cool the system to crystallize [Ca(P03)2]Ai. [Pg.144]

A first try was nothing more than heating about 200 g of monocalcium orthophosphate, contained in a platinum dish, to a melt near 1000 °C. This system was then slowly cooled and crystals formed, as expected. These crystals were removed from the dish as a dense cake about 2 cm thick. The cake was crushed and milled in various ways to determine if these crystals could in any way be considered fibers. [Pg.145]

The list of raw materials that could be used in this process is extensive. Soda ash or Trona could have been substituted for sodium hydroxide. Under some conditions limestone, CaC03, could be substituted for quicklime, CaO. There are several grades of phosphoric acid that might have been used, but I always insisted upon food grade materials even though they cost somewhat more than industrial grades. It is also possible to use sodium phosphates as monosodium orthophosphates for the sodium hydroxide and phosphoric used in the first plant. And, of course, it was possible to use calcium phosphates such as monocalcium orthophosphates. One requirement was paramount. If uniform melt was to form on the surface... [Pg.168]
