    摘要： A permanent, biocompatible material for soft tissue augmentation. The biocompatible material comprises a matrix of smooth, round, finely divided, substantially spherical particles of a biocompatible ceramic material, close to or in contact with each other, which provide a scaffold or lattice for autogenous, three dimensional, randomly oriented, non-scar soft tissue growth at the augmentation site. The augmentation material can be homogeneously suspended in a biocompatible, resorbable lubricious gel carrier comprising a polysaccharide. This serves to improve the delivery of the augmentation material by injection to the tissue site where augmentation is desired. The augmentation material is especially suitable for urethral sphincter augmentation, for treatment of incontinence, for filling soft tissue voids, for creating soft tissue blebs, for the treatment of unilateral vocal cord paralysis, and for mammary implants. It can be injected intradermally, subcutaneously or can be implanted.

    摘要： A process for producing a polycrystalline alumina sintered body which comprises the steps of:

    subjecting alumina powder to ultrasonic irradiation, mechanical stirring not using a grinding medium, or ultrasonic irradiation and mechanical stirring not using a grinding medium, resulting in slurry dispersed in a solvent;
    drying and forming said slurry to produce a green body; and then
    sintering said green body in an air atmosphere at a temperature in the range of 1400 °C to 1800 °C;
    wherein said alumina powder having a purity of 99.99 wt% or more comprises a polyhedral particle having substantially no fractured surface, and comprises α alumina particles having polyhedral shape; a D/H ratio of from 0.5 or more to 3.0 or less; the number-average particle size of from 0.1 µ m or more to 1.0 µm or less; a D90/D10 ratio of 7 or less.
