A METHOD AND APPARATUS FOR PRODUCING A HYDROGEN ABSORPTION ALLOY |
| 摘要 |
<p>A hydrogen absorption alloy with a high percentage of alloy is economically produced by the following method: (1) placing two or more kinds of fine metal particles M such as Mg and Ni adapted to form a hydrogen absorption alloy by alloying together with milling balls B in mill pots (21) of a high speed ball mill; (2) providing the internal part of the mill pots with a non-oxidising atmosphere; and (3) applying a composite milling acceleration ratio G of at least 30 to the internal part of each mill pot and setting the angular velocity ratio R of the revolution of the main shaft to the rotation of each mill pot to 1.9 or less, the composite milling acceleration ratio G being expressed by <MATH> where G : composite milling acceleration ratio; a max : composite milling acceleration (m/s<2>); g : acceleration of gravity (m/s<2>); omega 1 : angular velocity of revolution of the main shaft (1/S); K : revolutional diameter (m); N : internal diameter of mill pot (m); omega 2 : relative angular velocity of rotation of each mill pot with respect to the revolution of the main shaft (1/s); and R : omega 2/ omega 1. <IMAGE></p> |
