LASER-INDUCED VAPOUR-PHASE SYNTHESES OF BORON AND TITANIUM DIBORIDE POWDERS.

Article abstract of DOI:10.1007/BF01160795

Small diameter boron and titanium diboride powders were synthesized from vapor phase reactants heated with infrared radiation from a Co//2 laser. Boron powders were synthesized from BCl//3 plus H//2 gas mixtures from B//2H//6. TiCl//4 plus B//2H//6 gas mixtures yielded TiB//2 powder. BCl//3 plus H//2 plus TiCl//4 gas mixtures yielded TiCl//3 powder but no TiB//2. Novel equipment designed to vaporize TiCl//4 liquid is described. Detailed characterizations of the product powders are presented.
