manufacture example 1
[0290] Production Example 1: Production of Core-Shell Particles (C1-1)
[0291]
[0292] Put 186 parts of iron (III) chloride hexahydrate, 68 parts of iron (II) tetrahydrate and 1288 parts of water into the reaction vessel, make it dissolve and raise the temperature to 50°C, and keep the temperature at 50°C while stirring. 280 parts of 25% by weight ammonia water was added dropwise over 1 hour at 50 to 55°C to obtain magnetite particles in water. 64 parts of oleic acid was added as a dispersant to the obtained magnetite particles, and stirring was continued for 2 hours. After being cooled to room temperature, the magnetite particles adsorbed with oleic acid obtained by decanting for solid-liquid separation are washed with 1000 parts of water, the above-mentioned operation is carried out 3 times, and the operation of washing with 1000 parts of acetone is further carried out twice, Drying was carried out at 40° C. for 2 days, thereby obtaining magnetic metal oxide particles (...
manufacture example 5
[0310] Production Example 5: Production of Core-Shell Particles (C1-5)
[0311] In the "production of core-shell particles (PC)" in Production Example 1, 15 parts of tetraethoxysilane was used instead of 1200 parts of tetraethoxysilane, and in the "classification process of core-shell particles (PC)", Except setting the conditions described in Table 1, the same operation as Production Example 1 was performed to obtain core-shell particles (C1-5).
manufacture example 6
[0312] Production Example 6: Production of Core-Shell Particles (C1-6)
[0313] In the "production of core-shell particles (PC)" in Production Example 1, 150 parts of tetraethoxysilane was used instead of 1200 parts of tetraethoxysilane, and in the "classification process of core-shell particles (PC)", Except for setting the conditions described in Table 1, the same operation as in Production Example 1 was carried out to obtain core-shell particles (C1-6).
