Description

Пример 2. Испытани  на величину переохлаждени  кристаллогидрата, содерл ащего 19,8 г СаСЬ-бНгО и 0,2 г BaCl2-2H2O провод т при тех же услови х, что и в примере 1.Example 2. Tests on the magnitude of supercooling of the crystalline hydrate, containing 19.8 g of CaCI-bHgO and 0.2 g of BaCl2-2H2O, were carried out under the same conditions as in Example 1.

Величина переохлаждени  ДТ образцов кристаллогидрата CaCls-61420, содержащего BaCl2-2H2O, составл ет 2,0; 2,5; 3,0; 2,7; 2,8; 2,9; 2,0; 2,5; 2,0; 2,5; 3,0; 2,7; 2,5. При испытании кристаллогидрата, содержащего 0,4; 0,6; 0,8 вес. % кристаллогидрата хлорида бари , величина переохлаждени  не превышает 3°С. Таким образом, кристаллогидрат хлорида кальци , содержащий хлорид бари  или стронци , имеет величину переохлаждени The supercooling amount of DT samples of CaCls-61420 crystalline hydrate containing BaCl2-2H2O is 2.0; 2.5; 3.0; 2.7; 2.8; 2.9; 2.0; 2.5; 2.0; 2.5; 3.0; 2.7; 2.5 When testing crystalline hydrate containing 0.4; 0.6; 0.8 weight. % crystalline barium chloride hydrate, the supercooling does not exceed 3 ° C. Thus, calcium chloride crystalline hydrate, containing barium or strontium chloride, has the magnitude of supercooling.
