Effect of the atmosphere on the wetting of gold and platinum by sodium disilicate at 1000/sup 0/C using oxygen, nitrogen, carbon dioxide, argon, water vapor, carbon monoxide, hydrogen, and mixtures. Test pressures ranged from 10/sup -5/ mm Hg to almost one atmosphere. Results showed that the wetting of gold was unaffected by the atmosphere. The platinum-sodium silicate contact angle, on the other hand, was dependent on the nature and pressure of the gas. The results were interpreted on the basis of selective adsorption of the gases at the various interfaces and of absorption of oxygen and hydrogen by platinum.
