    • PURPOSE: A production method of three dimensional porous ceramic structures is provided to control pore size and shape, and porosity easily by using water soluble glass. The method is also applied to the production of porous metal or resin structures. CONSTITUTION: The porous ceramic structures are produced by the following steps of: (i) forming molten soluble glass to a shape of fiber(50-100micrometer of diameter) or sphere, wherein the molten soluble glass is prepared by grinding soluble glass based on Li2O-SiO2, K2O-SiO2, MgO-P2O5, CaO-P2O5, etc., melting ground soluble glass in a Pt crucible at 1450deg.C for 2hrs, and cooling; (ii) bonding glass fibers(or spheres) by heat-treating at 600-810deg.C for 5-10min or autoclave-treating for 1-5min under 1-3atm to form three dimensional network structures; (iii) filling pores of the structures with matrix through vacuuming or centrifuging, and then hardening; (iv) removing glass from the hardened structures by soaking matrix-filled structures in water or applying vapor pressure to structures. In the step (i), the glass fibers are obtained by drawing prepared glass with a burner and the glass spheres are obtained by grinding prepared glass, mixing with graphite which is an ideal mixing material in manufacturing glass, heating a mixture at 650-800deg.C for 1-10min in a furnace and washing the mixture with alcohol to separate graphite from glass.
    • 目的:提供三维多孔陶瓷结构的制造方法,通过使用水溶性玻璃容易地控制孔径,形状和孔隙度。 该方法也适用于生产多孔金属或树脂结构。 构成:通过以下步骤制备多孔陶瓷结构:(i)将熔融可溶玻璃形成为纤维(直径为50-100微米)或球形的形状,其中熔融可溶性玻璃通过研磨基于Li 2 O的可溶性玻璃制备 -SiO 2,K 2 O-SiO 2,MgO-P 2 O 5,CaO-P 2 O 5等,在Pt坩埚中将熔融的可溶性玻璃在1450℃下熔融2小时,并冷却; (ii)通过在600-810℃下热处理5-10分钟或1-3atm下高压釜处理1-5分钟将玻璃纤维(或球体)粘结形成三维网状结构; (iii)通过抽真空或离心将基质的孔结构填充,然后硬化; (iv)通过将基体填充的结构浸入水中或对结构施加蒸气压来从硬化结构中除去玻璃。 在步骤(i)中,通过用燃烧器拉制制备的玻璃来获得玻璃纤维,并且通过研磨制备的玻璃,与在制造玻璃中的理想的混合材料的石墨混合获得玻璃球,将混合物加热至650-800deg 在炉中加热1-10分钟,用乙醇洗涤混合物,将石墨与玻璃分离。
