A suspension comprising amorphous aluminum phosphate particles and a dispersant, in which the concentration of aluminum phosphate is between 40 and 70% by weight and the concentration of dispersant is less than 3.5% by weight based to the total weight of the suspension, in which the dispersant is selected from a phosphate dispersant selected from tetrasodium pyrophosphate, pentasodium triphosphate, trisodium dodecahydrate phosphate, tetrapotassium pyrophosphate, sodium and potassium triphosphate; and one of its combinations. |
