Preparation of Micrometer Fibres by the Organic-gel Method

Abstract

Abstract: Metallic nickel, alumina, magnesia fibres were prepared respectively by the organic-gel method from the raw materials of citric or lactic acid and their metal salts. The fibres featured with diameters of less than 1μm and fine crystalline particles of less than 100nm were obtained. The structure, thermo-decomposition process and surface morphologies of the fibres derived from thermal decomposition of the gel precursors were characterized by FTIR,XRD,DSC and SEM. The designability of fibrous textures was discussed as well. The experimental results indicate that the organic-gel method can be a promising process for preparation of micrometer fibres composed of nano-structured crystalline particles.

Key words: organic-gel method, nickel, alumina, magnesia, fibre
