氟化钙

Both CaCN2 and urea inhibited the chlamydospore germination, mycelial growth and sporulation of the pathogen, but CaCN2 by using at the rates of 0.5 and 1.0%, had two inhibition zones for chlamydospore germination with time while urea had only one. Calcium cyanamide was also more effective on reducing mycelial growth and sporulation of the pathogen than urea did. Therefore, the suppression of pea wilt might be due to fungicidal effect of the intermediate products including hydrogen cyanamide and urea from calcium cyanamide.

The novel vacuum furnace is employed in laboratory study. Compared with atmosphere magnesium carbothermic reduction furnace, this new one has the merits of high automation, easy manipulation and fine safety. Vacuum coking, vacuum carbothermic reduction process and magnesium vapory condensation process can be carried out in a furnace.

小型实验结果证明：还原温度升高，还原时间延长，氧化镁还原率增大，添加适量的氟化物对还原反应有促进作用；还原过程中真空度随时间的变化具有规律性，由此可以判断还原反应进行的速度与程度；真空中煤还原氧化镁的条件是：配料时保证C：MgO=3：1，并加入占总料重10％的氟化钙作为催化剂，尽可能的提高反应温度至1500℃以上，保温30～40分钟。
