ABSTRACT For nuclear waste vitrification in the Tank Waste Treatment and Immobilization Plant (WTP) at Hanford site, feed is charged into a continuously fed electric melter molten glass poured stainless steel containers to solidify. The heat from must be removed facility within plant operating constraints, making knowledge of thermal properties glasses critical. capacity low‐activity with syste...

It was established that at 298 K the molar heat capacity of alkali metal silicates 2 O· nSiO , Rb and Cs changes linearly when changing n from 1 to 4. Based on dependencies C o p,298 =f(n), values capacities O, O have been specified. Keywords: capacity, oxides metals.
