Abstract

The results of previous studies of whisker crystals were reviewed and analyzed in the materials of the article on non-traditional methods of growing whisker crystals, namely one of them – the "pull" of metal whiskers from melts. The analysis of data showed that the problem in modern conditions given enough attention, which undoubtedly be indicative of the relevance of research topic and, hence, these issues need to be addressed. The results of the literature review suggest that the crystallization front of whisker crystal delves into the supercooled melt zone and whiskers are growing during the experiments from the melt at a sufficiently high speed. If the seed material from crystallizing directly immersed into the melt and then pulled out of the melt with the material for the crystallization, the whisker growth rate decreases cardinally. Cooling and crystallization of the melt of metal whiskers accompanied by a bright flash, which indicates the allocation of considerable latent heat of crystallization and demonstrates the tremendous transformation rate of the liquid crystal in charge. Using a capillary device for "pulling" sapphire fibers from the melt showed that these fibers are uniquely single crystals. The research results confirmed that a major indicator of the degree of stretching is the strength of crystal whiskers. Registration and use of research to improve the implementation of environmental protection requirements of man and the environment given the fact that the range of use of whiskers in modern industry is expanded.
