Second step , the nanometer tin dioxide powder aspects are gone except the water of crystallizationsystem by the way of hydrothermal.
第二步，利用水热脱水法去除凝胶中的结晶水制得纳米二氧化锡粉体。
2
The various factors influencing the sedimentation effect of the crystallizationsystem were analyzed, and the measures taken for improving were proposed.
分析了影响结晶系统沉降效果的各个因素，提出了提高晶体沉降效果的改进措施。
3
Additionally a thyristor control will be supplied in order to adjust the slurry concentration in the crystallizationsystem in case of larger variations of the production parameter.
