摘要
P a hydroxyapatite is produced by the putting into contact continuously with a current of a slurry of lime slaked with a current of phosphoric acid to 60% by weight approximately relative to at least, in an approximately stoichiometric ratio of 10 ca (oh) 2 to 6 h3 po4 and at a temperature of approximately 80 to about 85°C, at a controlled ph of the reaction mixture comprised between about 9,0 11,0 approximately; it is calcined the hydroxyapatite at a temperature of at least 1 000°C, which gives a synthetic bone ash. / p & & p & this latter can be used in the manufacture of porcelain of bones (also called a porcelain or porcelain phosphatic english), which occupies a very important in the industry of the ceramic. / p
