Temperature Ranges of Deduction of Krypton in Glassceramics

Temperature dependences of krypton output from gas saturated glassceramic samples were determined by the method of thermodesorption spectroscopy. The samples were made by hot isostatic pressing the gas saturated preliminary sintered porous glassceramic samples. An initial material for manufacturing of glassceramics was the powder composition of 70% granite and 30% kaolin. It was shown that the glassceramics saturated by krypton up to 0,4% mass., at heating up to 850 degree K, completely keeps gases contained in it, and intensive gas evolution comes at heating above 1100 K. The glassceramics received by the given way can serve as a reliable material for immobilization of the gaseous products
