STUDIO A DIFFRACTION DE RADIOS X IN LE REACTION DE ACIDULATE FLUORURO CON ADAMANTE PULVERI-SATE.—Le solution acide reageva rapidemente con finmente particularisate adamante, con le formation de grande quantitates de fluoruro de calcium. In le presentia de plus grande particulas de adamante (44 a 250 μ), le formation de fluoruro de calcium esseva multo plus lente e pareva esser auto-limitatori post 2 horas. Un augmento in le crystallinitate esseva observate post 62 horas de tractamento. Un declino in le parametro del axe a indicava que un substitution de iones de fluoruro pro positiones oH habeva occurrite, resultante in le formation de un certe quantitate de fluorapatite.
