Sodium Hydroxide → Cerium nitrate

Participants

Reaction Steps

As an aluminum compound, a 2 mass % aqueous solution of aluminum chloride was prepared using 0.6 g of aluminum chloride hexahydrate. Further, a 2 mass % aqueous solution of cerium nitrate was prepared using 0.6 g of cerium (III) nitrate hexahydrate. These aqueous solutions were mixed to the suspension in the same manner as in Example 1 together with 8.0 g of a 1N aqueous solution of sodium hydroxide. The obtained filtered solid was washed and dried. Thus, a pearlescent pigment in which a layer containing hydroxides or hydrated oxides of cerium and aluminum is formed was obtained.
