The behaviour of one sort of Romanian diatomite as precursor in the synthesis of calcium and magnesium silicates was studied. The calcination of this diatomite, 3 h at 10000C in air, does not produce major modifications in structure and composition. In the same conditions, the thermal reaction between diatomite and calcium carbonate leads to a mixture of calcium silicates (CaSiO3, Ca2SiO4, Ca3SiO5) whereas the reaction product with magnesium oxide is orthomagnesium silicate (Mg2SiO4 - forsterite). This sort of Romanian diatomite can play the same role as other silica sources in the synthesis of alkaline-earth silicates.

LaSrSiO3N and LaBaSiO3N are the first examples of nitride-based alkaline earth orthosilicates with β-K2SO4 structure, and they show red-orange luminescence after activation with Eu2+. The analogous compound LaEuSiO3N is, in addition to a red phosphor material, a soft ferromagnet with a Curie temperature of 3 K.
