Aluminium Potassium Sulphate segmentation by type distinguishes five chemically and physically differentiated products that together shape the market’s supply‑side dynamics. The anhydrous crystalline form, representing roughly 25 % of volume, is preferred in high‑purity applications such as analytical reagents and specialty coatings because of its low moisture content and predictable solubility. Hydrated dodecahydrate crystals account for about 30 % and dominate the water‑treatment and paper sectors, where gradual dissolution moderates dosing rates. Micronized powders, comprising 20 % of sales, provide a finer particle size distribution that improves dispersion in textile mordanting and cosmetics, thereby commanding a premium price. Granular grades, at 15 %, are optimized for bulk handling in fire‑retardant and agricultural formulations, offering superior flowability and reduced dust generation. Finally, aqueous solutions, although a smaller niche at roughly 10 %, enable direct injection into process streams, eliminating the need for on‑site dissolution. Each type’s distinct performance profile explains its proportional contribution to the overall Aluminium Potassium Sulphate market.
