摘要： A pyrolytic boron nitride crucible is disclosed which is suitable for producing a single crystal of a semiconductor compound of Group III and V by the LEC method. The crucible comprises a side part and a bottom part. The bottom part has an absorption coefficient of light of wavelengths between 3,700 cm.sup.-1 and 6,500 cm.sup.-1 of at most 1.7 and/or the absorption coefficient of light of wavelengths between 3,700 cm.sup.-1 to 6,500 cm.sup.-1 of the bottom part is less than that of the side part by at least 0.5. In the crucible, the heat conduction from the bottom part to material melt in the crucible is strengthened, so that the convection flow of the material melt is suppressed and the temperature distribution in the crucible can be easily controlled.

摘要： An instrument and system for the preparation of a sample for analysis provides a crucible holder which improves the holding and control of a melting crucible during operation of the device for agitating a powdered sample and flux while being heated. The crucible holder is coupled to an agitation assembly which provides independently controlled operation on two different axes using separately adjustable variable frequency and amplitude motion along each of the two operating axes to provide an finite number of agitation patterns for the crucible. In one preferred embodiment of the invention, the heating flame is controlled by controlling the supply of compressed air and a combustion gas. In another preferred embodiment of the invention, a pilot burner is provided which both ignites the main burner located under the crucible and preheats the casting dish to a temperature which is substantially the same as the crucible. The pilot also can control air only flow directed to the casting dish for controllably cooling the sample melt to form the sample bead.
