An analysis of crystal structure of Ca-deficient oxonitridoaluminosilicate, Ca0.88Al0.91Si1.09N2.85O0.15

A polycrystalline, Ca0.88Al0.91Si1.09N2.85O0.15, was synthesized by a solid state reaction in the ternary system Ca3N2, AlN, and Si3N4, which was accompanied by a two-step heat treatment, 1600°C for 2 h and then 1800°C for 2 h under the nitrogen pressure of 0.92MPa. The space group of the polycrysta... View More
