Used as a precipitating agent for tannins and dyes in leather processing, enhancing the uptake of dyes and improving color fastness in textiles. Serves as a cross-linking agent in the formulation of antiperspirants due to its ability to form complexes with aluminum salts. Employed in the synthesis of zirconia-based catalysts and ceramic materials, where it acts as a precursor for high-temperature stable oxides. Applied in the paper industry to improve wet strength and as a retention aid in papermaking. Also utilized in the preparation of specialty chemicals for nuclear fuel processing due to zirconium’s neutron absorption properties.
