Summary
-
1.
The emanation method was used to study the processes occurring during the heating of barium phosphotungstate.
-
2.
The emanation of the salt at room temperature is higher, the higher its water content.
-
3.
Regardless of the initial water content of the original hydrates, the changes occurring during heating above 60‡ are the same in character.
-
4.
Over the temperature range from 100 to 200‡, where a large amount of water is lost, dehydration is not accompanied by a substantial change in emanation.
-
5.
Practically complete dehydration (350‡) is not connected with the decomposition of the heteropolyanion, which is quite stable and begins to decompose at 580‡.
-
6.
Barium phosphate and tungsten trioxide were found among the thermal decomposition products of barium phosphotungstate.
