    摘要:

    運(yùn)用熱失重法(TGA)分析研究TiH2的熱分解反應(yīng)性能。在真空條件下，分別以不同的升溫速率加熱TiH2粉末使之發(fā)生熱分解，失重開(kāi)始的溫度大致在550~580 ℃范圍內(nèi)，隨升溫速率的增加變化不大，略有升高；失重結(jié)束的溫度，隨著升溫速率的增加而升高；TiH2的失氫率隨升溫速率的增加而增加；隨著升溫速率的增加，TiH2失重所需時(shí)間減少

    Abstract:

    The heat decomposition of TiH2 was researched with a thermogravimetry (TGA) method. TiH2 powder was heated up at different heating rates under the vacuum condition, and then it was decomposed. The initial temperature of decomposition was between 550 and 580 oC, and did not greatly increase with increasing of the heating rate; but the termination temperature was increased. The mass loss of TiH2 decomposition increased with increase of the heating rate, but the time of TiH2 decomposition was reduced
