Authors: V.V. Soboliev, N.V. Bilan
Calculations of water solubility of mechanically activated quartz in the range of temperatures 300¸800 K are resulted. The suggested formula additionally takes into account the energy of one dislocation by introduction of the new coefficient, in which the differential heat of dissolution is also included, which on the average remains permanent in this range of temperatures. Upon these settlement dependences of quartz solubility on temperature at different values of dislocations concentration on the surface of quartz are plotted. It is set that solubility of the deformed quartz depends on temperature in less degree, than on the concentration of superficial active states. It is shown that the crystal accumulated energy which is proportional to the dislocations concentration – the active superficial centers – reduces the power barrier of chemical reactions of a new phase formation.
