Abstract
A welding flux binder and welding flux comprising the reaction product of a hydrolyzed and polymerized organometallic compound selected from the group consisting of metal alkoxides including tetraalkylorthosilicate, tetraalkylorthotitanate, tetraalkylorthozirconate and trialkylaluminate, metal esters, and metal oxalates. The organometallic compound is hydrolyzed and then polymerized to form a gel glass phase. Alkali and alkaline earth salts are added to stabilize and reduce the viscosity of the gel. The resulting welding flux binder and flux are non-hygroscopic and have a high fired strength.
