To explain the recent experimental observation of liquid-grown silicon nitride (Si{sub 3}N{sub 4}) crystals with a concave depression in the center of the (0001) end face, the authors propose a new growth mechanism and develop an analytical solution

Precipitation, growth, and coarsening of Si 3 N 4 crystals in (Si,Al,Mg,Y)(O,N) liquids at 1680°C has been studied. Contrary to the common observation in kinetics, coarsening rates of crystals in length and width are found to accelerate when the tot

Precipitation, growth, and coarsening of Si3N4 crystals in (Si,Al,Mg,Y)(O,N) liquids at 1680°C has been studied. The initial nucleation of β-Si3N4 occurs mostly on α-Si3N4 because of the very high supersaturation of the liquid. After a brief perio

Morphology evolution of β-Si3N4 grains on the end caps has shown significant dynamical features. It has been observed the (0001) growth front experiencing a shape transition on the caps from semisphere to negative-curved configuration. After our pre

X-ray diffraction was utilized to follow the transformation from β-SiC (3C) to the various α-SiC polytypes in the presence of AlN and Al2O3 additives after hot pressing from 1700 to 2100°C. The 2H- and 6H-polytypes of α-SiC were the predominate p

Additions of AlN and Al2O3 to β-SiC hot pressed at 2100°C strongly effect the β- to α-SiC phase transformation and the resultant α-SiC polytypes which are formed. Scanning and transmission electron microscopy were utilized to investigate the mic

A dense, oxygen-rich Y—α-sialon ceramic, with a small amount of YAG as a grain boundary phase, has been fabricated through GPS (gas pressure sintering). The effect of nitrogen pressure during GPS on densities and mechanical properties of the mater
