Solubilities of Ar, N 2 , CO 2 , and He in Glasses at Pressures to 10 Kbars

Glasses containing up to several percent of Ar, N 2 , and CO 2 were prepared at 2000 to 150,000 psi and up to 950°C and retained under ambient conditions. The solubilities are presented as a function of pressure, temperature, and composition of glass. Solubilities of O, He, and H 2 O were also investigated in various glass compositions, especially K 2 O–4SiO 2 and B 2 O 3 . The evolution of the gases at atmospheric pressure was followed by electron microscopy and density measurements.
