Abstract
Analysis of experimental data on the formation of β-sialon (β-Si6 – z Al z O z N8 – z ) at high temperatures (1300–1500°C) indicates that two morphological forms—fibers and spherical particles—differ in chemical composition:z = 3.58 in the fibers and 2.60 in the spherical particles. The formation of fibers is assumed to follow the whisker growth mechanism, while the spherical particles are likely to grow via diffusion.
