This book was released on 1969 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: The relation between the structure of SiC and its growth rate was studied at 2500 degrees C. The setting of the growth condition was improved by limiting the zone of recrystallization in the growth cavity. Super-saturation in the cavity was changed in several steps by the use of the cavity wall and thermo-insulator.

Available in PDF, EPUB and Kindle. Book excerpt: Several experiments were performed to clarify the process of carbon particle inclusion in crystals grown by Lely's sublimation procedure. Special attention was paid to the effect of the cavity wall, recrystallization temperature, and the increasing heating rate. It was found, using the technique of dark field photomicrography, that the density of the inclusions in the crystals often showed certain orientation and zonal structure. These features are explained by the microscopic temperature distribution and temperature fluctuation in a crystal. From the relation between the observed results and growth conditions, it was concluded that the phenomenon is attributed primarily to the shifting of the vapor phase composition in the growth cavity to the carbon side from the equilibrium condition.

Download or read book Relation Between Growth Temperature and the Structure of SiC Crystals Grown by the Sublimation Method written by Yoshizō Inomata and published by . This book was released on 1969 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: The relationship between growth temperature and the polytypes of SiC crystals has been studied experimentally at 2200 degrees C to 2600 degrees C under conditions of low supersaturation. The results are summarized as follows: (1) In the present experiment, excluding one example in which the 4 H-type was involved, the structure of all crystals consisted of the 6 H-, 15 R- and other long c-period types exceeding 21. Of the elemental structures of SiC, 2 H, 3 C, 4 H, 15 R, 6 H, and 21 R, only 6 H and 15 R were found. (2) In the range of 2200 degrees C - 2600 degrees C, 6 H and 15 R have the most thermal stability among the structures considered as elemental. However, the effect of impurity in the crystal and the shift from stoichiometry were neglected. (3) The relative amount of 15 R increased with decreasing temperature while 6 H showed the opposite tendency.
