Some conclusions have been drawn from the growth of KCl and AgCl optical fiber in the present paper. There is a temperature region with gradient near the solid-melt interface. The phase change latent heat is transmitted by the grown crystal. According to thermal transmission equation, the thermal conductivity (TC) in crystal, Ks, and that in melt, Km, near the solid-melt interface affect strongly on the temperature gradient along the grown axis in crystal and melt. Generally, thermal conductivity in crystal Ks is greater than that in the melt, Km. Similarly, K (metal) > K (nonmetal). TC of non-conducting crystal and metal will reduce with temperature increased TC in conducting liquid is 10 - 1000 times greater than that of non-conducting liquid. Halide ionic crystal with NaCl-type structure is nonconductor, whose TC Ks 1/T, in vicinity of melting point. However halid melt is conducting and its TC, Km, increases as greatly as to transcend the value of Kg. Therefore the temperature gradient in crystal is inevitably greater than that in melt near the solid-melt interface.© (1996) COPYRIGHT SPIE--The International Society for Optical Engineering.
