Abstract:
The present invention relates to a method for manufacturing a bioceramic porous material with improved mechanical properties and, more specifically, to a bioceramic porous material manufacturing method which controls a freezing crystallization phase of a sharp shape by using antifreeze and has high mechanical properties and high biocompatibility at the same time by providing the strength of a ceramic support which has a huge porous structure by including the following steps of: manufacturing ceramic slurry by using bioceramic powder, a binder, a dispersant, the antifreeze, and a freezing medium; forming a porous material which has a huge pore by foaming the ceramic slurry under a vacuum state; freezing and molding the porous material which has the porous pore below the freezing point of the freezing medium; forming a porous ceramic green body by freeze-drying a freeze-molded structure and removing the freezing medium; and treating the porous ceramic green body by heating.
Abstract:
PURPOSE: A bioceramics porous manufacturing method and the porous manufactured by the method are provided to manufacture the bioceramics porous in which the pore is connected well with more than 70μm of a huge pore. CONSTITUTION: A bioceramics porous manufacturing method comprises a step of manufacturing a ceramic slurry with an organism ceramic powder, a binder, a dispersing agent and a freezing medium; a step of primarily forming the slurry; a step of secondary forming the primarily formed ceramic slurry under the vacuum; a step of forming a ceramic green body by freezing the secondary formed ceramic slurry under a freezing point of the freezing medium; a step of forming a porous ceramic green body by freeze-dying the ceramic green body; and a step of heat-treating the porous ceramic green body.
