  • Patent number: 5271969
    Abstract: A metal oxide ceramic composite powder has crystals of a reacted and precipitated metal oxide distributed on fine particles of a ceramic material. The metal oxide is derived from an aqueous solution of metal chloride, which in the presence of a magnetic field, forms a complex ion solution. The complex ion may comprise a proportional blend of metallic and semi-metallic elements to produce specific properties. The complex ion is reacted and precipitated with an alkaline material to deposit a high purity metal oxide on the ceramic material. Each ceramic particle thus has a uniform coating of a high purity metal oxide deposited thereon.

  • Patent number: 5110774
    Abstract: A metal oxide-ceramic composite powder consisting of fine ceramic particles having a metal oxide coating firmly bonded to the surface thereof is molten at high temperature and then cooled to produce a material in the form of a solid solution in which the metal oxide component and the ceramic component are substantially homogeneously mixed together. Also, the metal oxide-ceramic composite powder is mixed with fine particles of a second ceramic and/or particles of a metal, and the mixture is baked to produce a sintered material.
