2. Description of the Related Art High-purity salts containing few impurities such as salt and refined salts are used in large amounts in the food industry and the like, but when exposed to the atmosphere, they absorb water in the atmosphere and solidify. If it is easily solidified, there is a problem in that not only the handling will be hindered but also the work efficiency will be reduced. Therefore, in order to prevent solidification, such as alkaline earth metal carbonates such as magnesium carbonate and calcium carbonate, inorganic oxides such as aluminum oxide and silicon dioxide, or aluminosilicate compounds such as sodium aluminosilicate and calcium aluminosilicate. A method of adding a water-insoluble finely divided inorganic compound to common salt or purified salt and mixing it is used.

However, when such a water-insoluble finely divided inorganic compound is added, solidification is effectively prevented unless the addition amount to salt or purified salt is about 0.2 to 0.5% by weight. Can not do it. Moreover, since the mixture of the finely divided inorganic compound and salt or purified salt is different in particle size, segregation phenomenon is likely to occur, which not only lowers the purity but also increases turbidity when dissolved in water.
