Abstract

The X-ray powder diffraction data for δ-Na2Si2O5 are reported. The sample was prepared from water glass solution applied to pressed powder tablets of finely ground quartz using a heating program with a maximal temperature of 700 °C. The crystallographic data for δ-disilicate obtained from a Rietveld analysis are: space group P21/n, a=8.3818(4) Å, b=12.0726(5) Å, c=4.8455(2) Å, β=90.303(5)°, V=490.31 Å3, Z=4, and Dcalc.=2.468 g/cm3.
