Title (EN) LIGHT-TRANSMISSIVE ZIRCONIA SINTERED BODY AND PREPARATION METHOD THEREFOR AND USE THEREOF
(FR) CORPS FRITTÉ EN ZIRCONE TRANSMETTANT LA LUMIÈRE ET SON PROCÉDÉ DE PRÉPARATION ET SON UTILISATION
(ZH) 透光性氧化锆烧结体及其制备方法与应用
Abstract:
(EN) Provided is a light-transmissive zirconia sintered body, obtained by preparing a green body from a powder for the light-transmissive zirconia sintered body by means of isostatic pressing, and sintering the green body at a high temperature and normal pressure after degreasing and biscuit firing. The light-transmissive zirconia sintered body is prepared by dispersing zirconia powder in water, adding an appropriate amount of a dispersant and a binder, mixing the mixture to form a slurry, and spray-granulating same, wherein the molar percentage of yttrium oxide in the zirconia powder is 3-5%. The light-transmissive zirconia sintered body can be used for preparing a fixed dental prosthesis.
(FR) L'invention concerne un corps fritté en zircone transmettant la lumière, obtenu par préparation d'un corps cru à partir d'une poudre pour le corps fritté en zircone transmettant la lumière par compression isostatique, puis frittage du corps cru à une température élevée et sous une pression normale après dégraissage et cuisson de biscuit. Le corps fritté en zircone transmettant la lumière est préparé par dispersion de poudre de zircone dans de l'eau, addition d'une quantité appropriée d'un dispersant et d'un liant, mélange du mélange pour former une suspension et granulation par pulvérisation de celle-ci, le pourcentage molaire d'oxyde d'yttrium dans la poudre de zircone variant de 3 à 5 %. Le corps fritté en zircone transmettant la lumière peut être utilisé pour préparer une prothèse dentaire fixe.
(ZH) 一种透光性氧化锆烧结体,其是将透光性氧化锆烧结体用粉体经等静压成型制成生坯,生坯经脱脂素烧后,在常压大气中进行高温烧结制得的。透光性氧化锆烧结体是将氧化锆粉料分散于水中,添加适量分散剂和粘合剂,混匀形成浆料,再通过喷雾造粒的方式制得的;其中,氧化锆粉料中氧化钇的摩尔百分比为3-5%。该透光性氧化锆烧结体可用于制备牙科固定修复体。
