Some Common Aspects of the Formation of Nonoxide Powders by the Vapor Reaction Method
As technology has advanced, needs for fine homogeneous powders have increased. Among many new powder preparation techniques, the vapor reaction method is receiving increasing attention as an important technique for producing powders of refractory oxides and non-oxides. Vapor-phase techniques are noted for their: (1) high purity powder products; (2) highly discrete particles or unaggregated powders; (3) ease of preparation of ultrafine powders with narrow particle size distribution; and (4) versatility for the direct preparation of metals, oxides and nonoxides.
