Abstract
The thermal expansion coeff. of cubic Si3N4 with the spinel structure was detd. with high temp. x-ray diffraction. The exptl. value agrees well with the lattice parameter predicted by first principles methods, and is significantly larger than the value for b-Si3N4. This difference is discussed in terms of the chem. bonding in these 2 modifications of Si3N4.
