2.5g/mL Density KBF4 Potassium Fluoborate CAS Number 14075-53-7

Product Description

Potassium Fluoborate is white powder or gel crystal. Non-hygroscopic and bitter in taste. Slightly soluble in water and hot ethanol, insoluble in cold ethanol and insoluble in alkali solution. Density (25/4℃) is 2.5g/mL, melting point is 530ºC.

White powder or gel crystal. Non-hygroscopic. Bitter taste. Crystallization from aqueous solution can produce hexagonal prismatic crystals. Relative density 2.50. Melting point 530℃. Slightly soluble in water and hot ethanol, but insoluble in cold ethanol. Begins to decompose when melted. It can be decomposed by strong acids such as sulfuric acid to form boron trifluoride. When melted with alkali metal carbonate, it forms fluoride and borate, which is toxic!

Physical Properties

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.


Packing

Packed in glass bottles and packed in cartons. 0. 5kg per bottle. Packaging: 1kg, 25kg, 200kg.
 

Inspection and maintenance

1. Regular inspection

Stored potassium borate should be inspected regularly to see if its packaging is intact and whether there are moisture absorption, caking, discoloration, etc. If problems are discovered, measures should be taken promptly to deal with them.

2. Maintenance

Clean and maintain the storage environment regularly to keep it dry, ventilated and tidy. At the same time, you should also check whether ventilation equipment, fire-fighting equipment, etc. are operating normally to ensure the safety of the storage environment.
