Open the CIPO recordAbstract From the Canadian patent
A method of making a metalloid precursor powder is disclosed, which powder avoids impurity localization and is effective to produce an improved fine grained ceramic body. A metalloid melt is formed and rapidly solidified into particles having a particle size distribution of 2- 50 microns; the particles are cooled at a rate to distribute impurities or additive metal ingredients substantially uniformly throughout the solidified particles with spacing between localizations being substantially in the range of 1-25 microns and the size of each localization being one micron or less. The cooling rate is equal to or greater than 105°C/second.
