【摘要】 利用自行研制的开放式大功率电解数据采集装置对由板状钛阴极,网状铂阳极和重水碱溶液组成的体系进行了一系列重复性的电解量热实验。测定了在100℃和70℃时,Ti Pt D2O体系的发热量变化和Ti阴极的晶体结构。实验结果与文献值比较显示,系统的"过热"量、"过热"效率和"过热"起始时间主要取决于电解液温度,同时与电解周期、阴极的形状、表面积等因素也有关。结果表明,在沸点附近通过电解重水产生可测、可靠和可重复的"过热"现象不一定需要很长时间。对电解产物的X射线衍射(XRD)分析肯定了电解前属六方晶系的α Ti大部分转变成立方晶系的β TiD2,并检测到了新的元素成份。在实验中没有观测到"滞后发热"现象。更多还原

【Abstract】 A series of electrolytic calorimetries have been carried out repeatedly for the system which consists of a Ti plate cathode, a Pt mesh anode and some deuteroxide lye by using a set of opened high-power electrolysis data processing apparatus made by ourselves. The variation of “excess heat” in Ti-Pt-D₂O system and the crystal structure of Ti cathode are measured round 100 ℃ and 70 ℃, respectively. Compared the data we’ve obtained with references’, the amount of “excess heat”, the efficiency to make “excess heat” and the onset time of “excess heat”, may be depended on the temperature of electrolyte in use mainly, and the cycle of electrolysis, the shape and surface of the cathode selected, and the like. Therefore, to produce a measurable, reliable and repeatable “excess heat” will not always spend a long time. Analysis data indicates that most of Ti belong to hexad cubic system of α-Ti changes to cubic system of β-TiD₂, and the existance of new elements in electrolytic products is determined. Another, the “heat of death” phenomenon is not observed in our calorimetry.更多还原
