THERMAL DECOMPOSITION OF gaz sf6 AND sf6 gas-AIR MIXTURES IN

Jan 01, 2013 · What causes the decomposition of sulfur fluoride on glass is the presence of H 2 0. The surface of the glass separator is always kept under vacuum in a flow of dried helium gas. So, the catalytic effect of "absent" H 2 0 should not occur. 419 K. BAUCOM: S0 2 and SOF2 can react with F 2 to form S0 2 F 2 and SOF4, respectively.Get price
