摘要： There is provided fine metal carbide particles which do not require pulverization of an initial material, a reaction intermediate and a product that causes the contamination with metallic impurities, which can promote a carbonization reaction uniformly at a lower temperature than in the past, and which can be manufactured at a low cost; and a method of manufacturing the same. The fine metal carbide particles are prepared by heat-treating, in a nonoxidizing atmosphere or a vacuum atmosphere, a solid obtained by drying an aqueous metal complex solution containing a water-soluble metal compound, and a low-molecular-weight water-soluble organic compound having one or more functional group(s) selected from the group consisting of amino group, hydroxyl group and carboxyl group, and having at least one of oxygen and nitrogen as heteroatom(s). In the fine metal carbide particles, the average particle diameter is 100 nm or less, the content of iron as impurities is 100 ppm or less, and the ratio of the total carbon amount is within ±0.3 wt % around a theoretical ratio of the total carbon amount calculated from the composition of the metal carbide.

摘要： A fibrous anisotropic permanent magnet is disclosed comprising fibers composed of an alloy comprising at least one of a rare earth metal selected from Nd, Pr, Dy, Ho, Tb, La, and Ce; Fe or Fe and Co; and B, said fibers having a mean diameter of from 50 to 1,000 .mu.m and exhibiting magnetic anisotropy. The fibrous anisotropy permanent magnet is prepared by extruding a molten alloy comprising at least one of Nd, Pr, Dy, Ho, Tb, La, and Ce; Fe or Fe and Co; and B in an oil to quench-solidify the molten alloy into a fibrous form.Since the fibrous magnet exhibits excellent anisotropic magnetic characteristics in the lengthwise direction of the fiber axis in the quench-solidified state, the magnet is particularly useful as a magnetic powder material for an anisotropic bond magnet.
