Applications
1. Used as flux in welding and raw material for manufacturing other fluoride salts. It can also be used in electrochemical processes and reagents.
2. Used as a flux for hot welding and brazing, a raw material for producing boron-containing alloys by aluminum-magnesium casting, and a filler in heavy-duty grinding wheels using resin as abrasive binder. When welding and fusing silver, gold and stainless steel, it can remove the dross of light metals. It is the raw material for making boron trifluoride and other fluoride salts. Also used in electrochemical processes and reagents.
3. Potassium borofluoride is used in low chromic acid chromium plating and lead-tin alloy electrolytes. Industrial products contain 95% potassium borofluoride. The content of chloride and sulfate in industrial products used for chromium plating must be controlled.
Storage
1. Should be stored in a cool, dry warehouse. Store in tightly sealed packaging to prevent damage to the packaging. During transportation, be sure to protect it from rain, sunlight, and moisture.
2. When potassium fluoroborate exceeds the melting point, it decomposes into toxic boron trifluoride gas. In the atmosphere, potassium fluoroborate is rapidly hydrolyzed due to the action of water vapor and produces white smoke, which is irritating to the skin, eyes, and especially the lungs. effect.
