  • Content Description: A method has been investigated and developed to grow TiB{sub 2} whiskers by the VLS mechanism. The reaction was carried out in a quartz tube 3 in. in diameter, 30 in. long at about 1150{degrees}C in the presence of a catalyst. The basic experimental parameters, a substrate, and a catalyst, for the growth of the whiskers have been defined. The whiskers produced have shown variable size and morphology depending on the experimental conditions, and location of the whiskers from the input port. The corrosion of the catalyst by the gas environment, and the gas distribution profile in the furnace had a serious effect on the reproducibility of the experimental results, and the overall yield of whiskers.
