The influence of B diffusion on the growth and shrinkage kinetics of oxidation-induced stacking faults (OSF) in silicon has been studied.On the one hand the Bdiffusion reduces the activation energy and increases the growth rate of OSF,on theother hand it reduces the density of OSF.The diffusion of boron atoms via inter-stitial mechanism enhances the diffusion of excess silicon interstitials and promotes thegrowth of OSF.The misfit dislocation,induced by B diffusion,suppresses the genera-tion of some OSF...

The influence of B diffusion on the growth and shrinkage kinetics of oxidation-induced stacking faults (OSF) in silicon has been studied.On the one hand the Bdiffusion reduces the activation energy and increases the growth rate of OSF,on theother hand it reduces the density of OSF.The diffusion of boron atoms via inter-stitial mechanism enhances the diffusion of excess silicon interstitials and promotes thegrowth of OSF.The misfit dislocation,induced by B diffusion,suppresses the genera-tion of some OSF and makes some OSF break and disappear during annealing,therefore,the density of OSF is reduced.

本文讨论了硼在硅中的扩散运动对氧化层错生长和收缩动力学的影响.一方面,硼的扩散运动降低氧化层错的激活能,使层错的生长速度增加;另一方面,却又抑制层错的产生和促使层错消失,使氧化层错的密度减小.在推填子扩散模型中,硼原子的扩散增强了过剩硅间隙原子的扩散,从而促进了层错的生长;而硼扩散引入的失配位错,在生长过程中抑制了某些层错的产生;在退火过程中又促使某些层错断裂和消失,从而降低了层错的密度.

Results obtained by varing manganese concentration, time and method of oxygen blowing revealed the reaction mechanism. The overall oxidation process proceeds in two steps, i. e. the simultaneous direct oxidation of both iron and manganese by oxygen gas at the gas-metal interface zone followed by the subsequent reaction between the slag formed in the first step and the metal at the...

The kinetics of oxidation of Fe-Mn melts by oxygen gas has been studied in a Mo-wire-resistance furnace at 1550℃. Results obtained by varing manganese concentration, time and method of oxygen blowing revealed the reaction mechanism. The overall oxidation process proceeds in two steps, i. e. the simultaneous direct oxidation of both iron and manganese by oxygen gas at the gas-metal interface zone followed by the subsequent reaction between the slag formed in the first step and the metal at the slag-metal interface zone, with the iron oxide in the slag reduced by Mn in the metal. Using the assumption and the methods developed by D.W. Krevelen; Sketa; Iwao Muchi, numarical calculations have been conducted with a digital computer. The calculated results are in quite good agreement with the experimental data. The ratio of the rate constants of direct oxidation of Fe and Mn at 1550℃ obtained by extrapolating experimental data to zero time is:k2/k1=39

在1550℃钼丝炉中,对氧气与液态铁锰合金反应的动力学进行了研究。根据改变锰的浓度和供氧时间及供氧方式所得到的实验结果,推测了反应动力学机理。 实验结果表明,氧气与液态铁锰作用的全过程由以下两个步骤组成:在氧气-金属熔体直接接触界面上,铁、锰同时氧化;接着,直接氧化生成的渣在渣-金属熔体界面续继反应,渣中氧化铁被金属中的锰还原。 根据上述机理,运用Krevelen、佐田、鞭磁的假设和数学分析方法,在计算机上进行了计算。计算结果与实验结果符合得比较好。 将实验数据外推到零时刻,便得到1550℃时锰和铁的氧化反应速度常数之比为: K_2/K_1=39

Methods for reduction of hexavalent uranium to the trivalent state by the liquid-zinc-amalgan and mercury cathode electrolysis have been investigated in hydrochloric and sulfuric acid solutions. The percentages of reduction were determined with different media, various acid concentrations, uranium concentrations and the time of electrolysis. It was found that the hexavalent uranium was quantitatively reduced to trivalent state by mercury cathode electrolysis. The stability of uranium (Ⅲ) in various hydrochloric acid solution was measured in the air and nitrogen, and the kinetics of oxidation of uranium (Ⅲ) proceeded reasonably to be a first order reaction in the air. The absorption spectra of uranium (Ⅲ) in hydrochloric acid solution were examined.
