摘要:
A ferrite magnet having a basic composition represented by the following general formula: (A1−xRx)O.n[(Fe1−yMy)2O3] by atomic ratio, wherein A is Sr and/or Ba, R is at least one of rare earth elements including Y, M is at least one element selected from the group consisting of Co, Mn, Ni and Zn, and x, y and n are numbers meeting the conditions of 0.01≦x≦0.4, [x/(2.6n)]≦y≦[x/(1.6n)], and 5≦n≦6, and substantially having a magnetoplumbite crystal structure, is obtained by uniformly mixing a compound of Sr and/or Ba with an iron compound; calcining the resultant uniform mixture; adding a compound of the R element and/or the M element to the resultant calcined powder at a pulverization step thereof; and sintering the resultant mixture. The compound of the R element and/or the M element may be added at a percentage of more than 0 atomic % and 80 atomic % or less, on an element basis, at a mixing step before calcination.

Disclosed is an agricultural chemical composition in the form of an aqueous suspension, which comprises fine particles of a water-insoluble physiologically active substance having a melting point of 15.degree. to 70.degree. C., which are stably dispersed in water by a water-soluble or water-dispersible polymer comprising at least one monomer selected from the group consisting of unsaturated carboxylic acids and derivatives thereof as the indispensable component, as a dispersant, and a phthalic acid ester as an agent for preventing precipitation of crystals.In this agricultural chemical composition, the phthalic acid ester bleeds on the surface of the physiologically active substance to modify the surface, and the storage stability of the composition in the form of a suspension is highly improved.
