Abstract

The change in sodium trimetaphosphate by grinding at low pressure was examined by the X-ray diffraction method and paper chromatography. The crystalline sodium trimetaphosphate became amorphous more rapidly when ground at low pressure than in dry air or nitrogen gas, and in these cases the chain phosphates higher than triphosphate were produced in addition to ortho-, pyro- and tri-phosphates.
