| description | Provided is a method for preparing hexaferrite magnetic powder. The method for preparing hexaferrite magnetic powder may comprise the steps of: preparing a base powder by mixing a first source powder comprising a metal oxide, a second source powder comprising iron oxide, a third source powder comprising calcium, and a fourth source powder comprising a salt; synthesizing hexaferrite magnetic powder by heat-treating the base powder at a temperature higher than the melting point of the fourth source powder; and removing the fourth source powder remaining in the hexaferrite magnetic powder by washing the hexaferrite magnetic powder.
Est fourni un procédé de préparation d'une poudre magnétique d'hexaferrite. Le procédé de préparation d'une poudre magnétique d'hexaferrite peut comprendre les étapes consistant à : préparer une poudre de base en mélangeant une première poudre source comprenant un oxyde métallique, une deuxième poudre source comprenant un oxyde de fer, une troisième poudre source comprenant du calcium et une quatrième poudre source comprenant un sel ; synthétiser une poudre magnétique d'hexaferrite par traitement thermique de la poudre de base à une température supérieure au point de fusion de la quatrième poudre source ; et retirer la quatrième poudre source restant dans la poudre magnétique d'hexaferrite en lavant la poudre magnétique d'hexaferrite.
