Ceramic fibers are being used to improve the mechanical properties of metal matrix and ceramic matrix composites. This paper reports a study of the structural and other microstructural characteristics of silicon nitride whiskers using both conventional TEM and high resolution electron microscopy.The whiskers were grown by T. E. Scott of Michigan Technological University, by passing nitrogen over molten silicon in the presence of a catalyst. The whiskers were ultrasonically dispersed in chloroform and picked up on holey carbon grids. The diameter of some whiskers (<70nm) was small enough to allow direct observation without thinning. Conventional TEM was performed on a Philips EM400T while high resolution imaging was done on a JEOL 200CX microscope with a point to point resolution of 0.23nm.

The investigating results are given on the process parameters' influence on the phase and structure formation in the course of the B4C based materials' reactive sintering under the Si molten presence. The interaction of the B4C particles and carbon with the molten silicon was regarded during the reactive sintering. The negative effect of the B4C particles' dissolution in the molten silicon within the reactive sintering was noticed. The methods to raise the boron carbide particles' content in the ceramics based on the reactively sintered boron carbide were discussed.Ill. 10. Ref. 24. Tab. 1.
