    • The invention provides submicron particles. The invention further provides submicron particles which are dispersed in an aqueous colloid. The invention further provides a method of forming the stable dispersion which includes providing an ion exchange resin, loading the ion exchange resin with an ion, treating the loaded resin to form nanoscale particles. The invention further provides fluidizing the resin and particles to form an aqueous stable colloid.
      The invention further provides low optical density magnetic fluid which is a stable dispersion of fine magnetic particles. The invention further provides a method of forming the stable dispersion which includes providing an ion exchange resin, loading the ion exchange resin with an ion capable of forming a magnetic phase, treating the loaded resin to form magnetic particles and micronizing the resin and magnetic particles in a fluid to form an aqueous stable colloid.
    • 本发明提供了亚微米颗粒。 本发明提供了进一步的亚微颗粒分散在其中wässrige胶体。 本发明进一步提供形成稳定的分散体,其包括:提供离子交换树脂,在离子与加载的离子交换树脂,处理所加载的树脂以形成纳米级颗粒的方法。 本发明提供另外的流化树脂和粒子以形成在wässrige稳定的胶体。 本发明进一步提供低光密度的磁性流体的所有其是磁性微粒的稳定分散体。 本发明进一步提供形成其包括提供离子交换树脂的稳定的分散体,在能够形成磁性相,处理所加载的树脂以形成磁性颗粒和微粉化的树脂和磁性颗粒的离子与加载的离子交换树脂的方法 的流体,以形成在wässrige稳定的胶体。
