Physical characteristics: the product represents white crystal powder or the sand - amount of detailing, and pinkish crystal powder or the sand - amount of detailing, and also.
Sp. gr.2.95 - 3.01g/cm3, melting temperature about 1000 Celsius, specific 1.056j/g is Celsius warm the 18 - 100th to Celsius
It it is a little soluble in water, but insoluble in anhydrous fluoric hydrogen. Content of its crystal water will decrease at increase in the molecular relation therefore its losses when calcinating will be also have decreased while increase in the molecular relation. After paste from synthetic cryolitas from different molecular dehydrates a ratio of losses when calcinating in 800 Celsius there will be 10,34% , 6,22% and 2,56% when the molecular relation reaches 1,74, 2,14 and 2,63 reaktivno.
