摘要： A process for treating a nitride-containing ceramic material which includes (1) comminuting the material to produce a particulate ceramic material having a particle size distribution such that at least 40% by weight of the particles have an equivalent spherical diameter (esd) smaller than 2µm; and
(2) a ferrosilicon separation step comprising one or both of the following steps:
a) subjecting the particulate ceramic material produced in step 1 to differential sedimentation in a liquid medium to produce substantial separation of a light fraction from a heavy fraction, ferrosilicon required to be separated being included in the heavy fraction and refined particulate ceramic material being included in the light fraction; b) subjecting a suspension of the particulate ceramic material to magnetic separation to produce substantial separation of magnetic particulate material from non-magnetic particulate material, refined particulate ceramic material being included in the non-magnetic material.

摘要： This invention is a multi-phase SiA1ON composite having a first or alpha-SiA1ON phase prepared from a multi-cationic mixture including oxides and nitrides of strontium, at least one of yttrium or a rare earth metal, and at least one other metal such as Ca, Mg, Li or Na. The composite also has a second or beta-SiA1ON phase, and a third phase of intergranular amorphous morphology including Si, A1, O and N combined with a mixture of strontium, at least one of Ca, Mg, Li or Na and at least one of yttrium or a rare earth element. The material is useful for high wear, high temperature machine or engine components and tools. The composite is prepared from a mixture of Si3N4. A1N and a multi-cationic composition that includes (1) an oxide or nitride of Sr, (2) at least one compound selected from oxides and nitrides of Ca, Mg, Li and Na and (3) at least one oxide or nitride of Y or rare earth elements.
