  • Permanent magnet with inter-grain heavy-rare-earth element, and method of producing same
    Patent number: 11830645
    Abstract: A manufacturing method of a sintered magnet is described. The method includes forming a pre-sintering body from a first magnetic powder and a second magnetic powder (containing a heavy rare earth element, HRE) so that at least part of the second magnetic powder is provided at at least one inner portion of the pre-sintering body and surrounded format least two opposite sides by the first magnetic powder; sintering the pre-sintering body; and annealing the sintered pre-sintering body at an annealing temperature lower than the sintering temperature, thereby causing inter-grain diffusion of HRE from the HRE reservoir zone to the grain boundary phase. After the annealing, the grain boundary phase contains the HRE in a higher concentration than the main phase.

  • Multi-layer ceramic composite material with a thermal-protective effect
    Patent number: 7118802
    Abstract: A two-layer ceramic composite material, wherein the first predominantly load-bearing layer is an oxidic, carbon-free fiber-reinforced ceramic layer which is made by a colloidal process. The second predominantly thermally insulating layer is an oxide-ceramic foam. The colloidal process produces carbon-free oxide ceramics which, because of their high purity, have low dielectric losses in the entire usage temperature range. In addition, the colloidal process provides a simple and cost-effective production method.
