Description

Formation of crystal phases in lithium-tungsten phosphate(1) and lithium phosphate(2) glasses was studied. It was shown that formed crystal phases didn't limit hydrogen mass transfer; the value of effective coefficient of volume diffusion DT of hydrogen (tritium) isotope at temperature which is below by 150 deg C the temperature of glass crystallization, equals 4.3x10-8 cm2/s in 1, -5.5x10-8 cm2/s - in 2. It was established that DT value was related with the degree of stability of oxygen radicals and the total content of hydrogen
