Considering the experimental methods used and results obtained by previous investigators on the preparation of silicon carbide by gaseous cracking, we have performed our experiments in a similar carbon plate resistance furnace in an atmosphere of hydrogen, argon or nitrogen at temperatures from 1400 to 2200℃. The vapor reacting agents used are either SiCl_4,CH_3SiCl-3, (CH_3)_3SiCl or the mixture of toluene and SiCl_4 or (CH_3)_3SiCl。Having examined carefully under polarising microscope, we revealed with...

Considering the experimental methods used and results obtained by previous investigators on the preparation of silicon carbide by gaseous cracking, we have performed our experiments in a similar carbon plate resistance furnace in an atmosphere of hydrogen, argon or nitrogen at temperatures from 1400 to 2200℃. The vapor reacting agents used are either SiCl_4,CH_3SiCl-3, (CH_3)_3SiCl or the mixture of toluene and SiCl_4 or (CH_3)_3SiCl。Having examined carefully under polarising microscope, we revealed with no exception that all of the crystal grains of silicon carbide grown over the above-mentioned temperature range contain skeletons of alpha-silicon carbide platelets, with beta-silicon carbide forming a matrix. Intergrowth of the C planes of alpha-silicon carbide with beta-silicon carbide was observed. The twinning angles of the C planes in alpha-silicon carbide crystal were determined to be 37.3°and 70.2°By calculating the temperature dependence of the free energy change of the possible chemical reactions with SiCl_4 in silicon carbide formation, it has been shown that these reactions can be grouped into three catagories: (1) the decomposition of SiCl_4, (2) the decomposition of hydrocarbons or the syntheses of simple hydrocarbons, and (3) various possible reactions leading to silicon carbide formation. The reactions with methyl chlorosilanes as reacting agents have also been discussed.As a consequence of this investigation, the problem of controlling the crystalline modification during the synthesis of silicon carbide monocrystals by the gaseous cracking method is emphasized, and it is believed that the better solution of this problem would be of no less importance than to increase its crystal size or purity.

本文考虑了前人的研究条件和结果之后在类似的碳片炉内进行了裂化法合成碳化硅的实验,反应试剂为SiCl_4、CH_3SiCl_3、(CH_3)_3SiCl或SiCl_4及(CH_3)_3SiCl与甲苯的混合蒸气,气氛为H_2、Ar或N_2,温度为1400~2200℃。岩相法观察表明,在实验温度范围内制备的碳化硅晶粒内都包含α-SiC晶体的片状骨架,它们往往沿C画与β-SiC相间互生:α-SiC晶架的C面孪晶角为37.3°和70.2°;β-SiC则形成基体物质。 化学反应的自由能变化与温度的依赖关系的计算表明,裂化法的化学作用可以概括为以下三类:(1)SiCl_4的分解反应;(2)碳氢化合物的分解或简单碳氢化合物的介成反应;(3)各种可能合成碳化硅的反应。此外,也讨论了氯化硅烷反应剂系统的裂化反应。 根据实验结果,提出了裂化法生长β-SiC单晶的晶型控制问题,并认为解决这;一问题的重要性应不亚于晶体的大小与纯度。

The flow characteristics of the liquid and solid phase in a multi-stage flui-dized bed with down comers was studied systematically in the following aspects: (1) the longitudinal back-mixing of the liquid phase, (2) the pressure drop of the liquid flowing through the perforated distribution plate, (3) the gravity flow of the solid particles through the bottom aperture of the downcomer pipe, and (4) the working characteristics of the downcomer pipe.

In order to increase the productive capacity of the small-sized gas-liquid mass transfer units, the structure of double overflow inclined hole tray with gas edge sealing has been proposed. Such a tray structure has solved the problem which arises from edge sealing when the small-sized plate columns are used, and is applied in production. It gives a good result. This proves that it can be widely used in smallsized columns with high productive capacity, smaller equivalent height, convenient manufacture...

Such a tray structure has solved the problem which arises from edge sealing when the small-sized plate columns are used, and is applied in production. It gives a good result. This proves that it can be widely used in smallsized columns with high productive capacity, smaller equivalent height, convenient manufacture and low cost.
