    摘要： A ceramic color composition for coating a glass plate with the same includes first and second inorganic pigments, an optional filler, a low melting point glass frit, a resin and an oil. The total of the first and second inorganic pigments and an optional filler amounts to "A" parts by weight. The low melting point glass frit amounts to "B" parts by weight. The first and second inorganic pigments have average particle sizes ranging from 0.1 to 1.5 .mu.m and from 2 to 50 .mu.m, respectively. A ratio of "A" to the total of "A" and "B" ranges from 0.08 to 0.40. A ratio of the amount by weight of the first inorganic pigment to the total of "A" and "B" ranges from 0.05 to 0.25. A ratio of the amount by weight of the second inorganic pigment to the total of "A" and "B" ranges from 0.03 to 0.15. The ceramic color composition is substantially improved in releasability of the same from a bending press mold.

    摘要： Fine particles of a ferrite having the magnetoplumbite structure are prepared by hydrothermal treatment of .gamma.-Fe.sub.2 O.sub.3 and at least one compound of a divalent metal selected from Ba, Sr and Pb in an aqueous alkali solution, preferably at 80.degree.-360.degree. C. This process is suitable for preparation of hexagonal and thin plate-shaped particles of the ferrite and is advantageous in consuming only a small quantity of alkali. Alternative to .gamma.-Fe.sub.2 O.sub.3, it is possible to use either Fe.sub.3 O.sub.4 or an intermediate iron oxide expressed by (FeO).sub.x.Fe.sub.2 O.sub.3, where O

    摘要： High purity hexagonal plate-like .alpha.-Fe.sub.2 O.sub.3, commonly called micaceous iron oxide, is prepared by a hydrothermal treatment of either magnetite or an iron ore, or an iron oxide, of which principal component is magnetite together with an oxidizer in an aqueous alkali solution. Main advantage of this process is a great decrease in the consumption of alkali. Pure magnetite for use in this process can be prepared economically by a hydrothermal treatment of an iron ore, or an oxide, of which principal component is an oxide of trivalent iron in an aqueous alkali solution together with a compound of divalent iron and/or metallic iron.
