Used as a corrosion-resistant coating in metal surface treatments, especially for aluminum and magnesium alloys. Acts as a binder in refractory materials and foundry sands due to its excellent thermal stability and adhesive properties. Employed in the production of abrasives and grinding wheels where high mechanical strength and heat resistance are required. Also utilized in ceramic formulations to enhance strength and durability at elevated temperatures. Shows application in fireproofing materials and intumescent coatings owing to its ability to form protective ceramic layers when exposed to high heat.
