Synthesis of cryolite by fluoride aluminum complex solution .
利用氟铝络合物溶液合成冰晶石的研究。
But aluminium has a fairly low melting point and its oxide can be dissolved in a substance called cryolite that also has a low melting point , so the amount of heat needed is manageable .
In the present investigations both integral and partial onthapis of solution of alumina in molten cryolite were determined as a funetion of composition with a high teupercature calorimeter .
