我们在党委的领导和鼓舞下,克服许多新发生的困难,经过了两个月的试验,基本上认为用食鹽代替纯碱生产冰晶石是可以用于工业生产的。我们认为这对于发展煉铝事业有一定意义的。为了得出一些初步资料,首先在试验室里进行了小型试验。(一)全部用食鹽代替纯碱制做冰晶石制做方法:1.先制成氟铝酸将氟氢酸(一定量的)放入铝罐内加热70℃即 After the leadership and encouragement of the party committees, we have overcome many new difficulties and after two months of experiments, we basically think that using salt instead of soda ash to produce cryolite can be used for industrial production. We think this is of some significance for the development of aluminummaking. In order to come up with some preliminary information, we first conducted a small experiment in the laboratory. (A) all salt instead of soda ash made of cryolite system made: 1. First made of fluoroaluminate Hydrogen fluoride (a certain amount) into the aluminum cans heated to 70 ℃ that
