| description | 22Dispersion comprising water and mixed potassium silicon oxide powder, where-the mixed oxide powder is in the form of aggregates of primary particles, has a BET surface area of 100 to 400 m/g, has an average aggregate diameter in the dispersion of less than 100 nm, and possesses a potassium fraction of 0.05% to 1.5% by weight, calculated as KO and based on the mixed oxide powder, and-the dispersion has a fraction of mixed oxide powder in the dispersion of 25% to 40% by weight, the sum of water and mixed oxide powder is at least 98% by weight and the pH is 9 to 11.5. |
