氢化钛中氢的理论含量可达4％。本文将着重探讨大量氢存在下,对氧测定的影响,以及为了克服这种影响,采用了事先真空加热预处理氢化钛试样的方法。建立了高频加热惰气熔融测定氢化钛中氧的分析方法。实验部分 (一)高含量氢对氧测定的影响试验表明,采用高频加热惰气熔融库仑滴定法测定氢化钛中氧时,随着试样重量的增加,亦即试样中含氢量的增加,测得氧含量明显地偏低。为了观察氢含量对氧测定的实际影响,将氢化钛试样在高真空下,用不同温度加热处
The theoretical content of hydrogen in titanium hydride can reach 4%. This article will focus on the presence of a large amount of hydrogen in the determination of oxygen, and in order to overcome this effect, the use of pre-vacuum preheating titanium hydride sample method. A method for the determination of oxygen in titanium hydride by high frequency heating inert gas fusion was established. Experimental part (A) of the impact of high hydrogen content of oxygen test showed that the use of high frequency heating inert gas melting coulometric titration of titanium hydride oxygen, with the sample weight increases, that is, the sample containing hydrogen content Increase, measured oxygen content was significantly lower. In order to observe the actual effect of the hydrogen content on the oxygen determination, a sample of titanium hydride is heated under high vacuum at different temperatures
