Property: colorless, odorless, tasteless, strongly alkaline.
Solid type: white powder or granules, hygroscopic, readily soluble in water. The aqueous solution may absorb CO2 and form aluminum hydroxide precipitate. Addition of NaOH is required to increase stability.
Liquid type: transparent slurry, stable during storage life. Prolonged stay of diluted aqueous solution may cause aluminum hydroxide precipitate.
Concrete engineering: used in combination with water glass as concrete adhesive; concrete solidifying agent, promotes concrete solidification.
Papermaking: used in combination with aluminum sulfate as filling agent.
Water treatment: flocculant aid, reduces water hardness and accelerates floc settling.
Petrochemical: catalyst or catalyst carrier, coating primer.
Others: in textile, dye/printing, pharmacy, rubber, detergent, metal surface treatment, etc.
