The Chemical Reactions in Solution Synthesis of Aluminum Alloy Brazing Fluorate Flux

Abstract:

Based on experiment, preparation method, formation mechanism and reaction process in was studied ,in which phase analysis was adoped. melting method and wet synthesis are separately used to produce ternary flux.it has been found that product will be different by using the method of steaming and filtering in the process of preparing Potassium fluoroaluminate. K₂AlF₅ is very easy to get as well as Cesium fluoroaluminate.Result of ternary flux is not the way we hoped it would be for the melting point is above 520°C.
