摘要
在纳米镍粉中添加烧结剂,于不同低温下进行烧结得到轻烧结体,作为贮氢材料。采用BET装置,通过改变系统压力,测定氢气的吸附量,得出不同条件下纳米镍轻烧结体对氢气的吸附规律,确定纳米镍轻烧结体的最佳制备条件。最佳制备条件为:25%烧结剂,烧结温度400℃,烧结时间2 h。
Sinter flux is added to nano-nickel powder to get the light sintered body at different temperature, as the material to store hydrogen. With a BET device, we measure the amount of absorbed hydrogen by changing the pressure and obtain the absorption principle nano-nickel light sintered body to hydrogen at different conditions. The optimal condition is. 25% sintered flux, temperature 400 ℃, the sintered time 2 hours.
