Abstract:
The invention relates to mixtures of aluminum phosphite with sparingly soluble aluminum salts and nitrogen-free extraneous ions, comprising 80 to 99.898% by weight of aluminum phosphite of the formula (I) Al2(HPO3)3xH2O (I) in which x is 0 to 4, 0.1 to 10% by weight of sparingly soluble aluminum salts and 0.002 to 10% by weight of nitrogen-free extraneous ions; to a process for preparation thereof and use thereof.
