Used as a heavy liquid in mineral separation due to its high density when dissolved in water, allowing for precise separation of minerals based on specific gravity. Commonly applied in geology and material science for sink-float separation techniques. Also utilized in centrifugation processes for isolating particles in soil analysis and recycling industries. Its non-toxic and environmentally friendly profile makes it a preferred alternative to hazardous heavy liquids. Additionally, it serves in the preparation of tungsten-based catalysts and functional materials.
