    摘要: In order to reduce the tendency to decompose of particles or granules of alkali metal chlorites and to enhance their stability, said particles or granules are completely coated with an inorganic salt or a mixture of such salts which are compatible with the chlorite and with each other, e.g. nitrates, carbonates, bicarbonates, phosphates, silicates and chlorides, especially alkali metal salts and alkaline earth metal salts thereof. The coating may be carried out by any conventional coating process, e.g. by contacting the particles with a solution of the stabilizing salts under vaporizing conditions in a rotating inclined disk, a rotary drum, or in a fluidized bed.
