The method of making the cure rate of the magnecium phosphate cement delay

摘要

(57) Abstract Being the method of making the cure rate of the magnecium phosphate cement delay, although it rises pH to water combination ones of the magnecium phosphate cement of hardening or part hardening, in this method, and MgO/Mg (OH) makes the melting of ₂ minimum at the sufficient quantity, including the fact that the appropriate base is added, it is the method of becoming. The appropriate magnecium phosphate cement includes the ammonium phosphate magnesium cement and the potassium dihydrogen phosphate magnesium cement.
