✦ Synopsis

Silico-phosphate glasses of NaCaPO 4 -SiO 2 and NaCaPO 4 -AlPO 4 -SiO 2 system have been the subject of the presented investigations. Glasses of these systems are the basis for the preparation of glassy-crystalline biomaterials [R. D. Rawlings, Clin. Mater. 14 (1993) 155]. Detailed knowledge of the precursor glass structure is necessary for proper design of the glassy-crystalline biomaterials preparation procedure. Since there is no long-range ordering in glasses, spectroscopic methods which make it possible to study the short range ordering should be applied.

MIR studies carried out in the work have allowed to establish that the glasses of the systems studied show domain composition [
