  • Reaction of Fluorapatite with Aluminium Phosphate

抄録

Effect of aluminium phosphate (AP) on defluorinating-reaction of fluorapatite (FAp) was studied. The decomposion rate of FAp and its fluorine volatility were measured under several atmospheres and various heating conditions.<BR>The decomposition was active above 1050°. The decomposition reaction was more preferable to the volatilization reaction in a nitrogen atmosphere, whereas the rate of above reactions were nearly equal in nitrogen-water vapor atmosphere. In the FAp-AP-H2O system, H2O acted to accelerate the decomposition and the volatilization. On the other hand, when SiO2 was used in place of AP, SiO2 itself was considered to accelerate the above reactions.
