The X-ray powder diffraction data for δ- Na 2 Si 2 O 5 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 P 2 1 / n , a =8.3818(4) A, b =12.0726(5) A, c =4.8455(2) A, β=90.303(5)°, V =490.31 A 3 , Z =4, and D calc . =2.468 g / cm 3 .
