Abstract
This invention pertains to the use of tin oxide as a corrosion resistant erial for preventing or inhibiting high temperature corrosion by molten sulfate-vanadate deposits and gaseous sulfur trioxide formed in engines or other high temperature apparatus which burn materials containing sodium, sulfur, and vanadium.
Claims16
A method of inhibiting corrosion at high temperature comprising the step of contacting a structural member with oxides of sodium and sulfur at a temperature of about 300.degree.-1500.degree. C., the structural member comprising a tin oxide.
A method of inhibiting corrosion at high temperature comprising the steps of:
- a) combusting a material which contains sodium, vanadium and sulfur to form reaction products which contain oxides of sodium, vanadium and sulfur, and
- b) contacting a structural member with the reaction products at a temperature of 300.degree.-1500.degree. C., the structural member comprising tin oxide.
