The present invention provides a method for manufacturing an aluminum electrode using a solution process and an aluminum electrode manufactured thereby. The manufacturing method includes the steps of: manufacturing an aluminum precursor solution for the solution processing using AlHas a basic material before forming aluminum; coating the aluminum precursor solution on a substrate through the solution process and drying the aluminum precursor solution; and forming a low work function aluminum electrode through a low-temperature baking process at the temperature of at most 150&#xb0; C. The method for manufacturing the aluminum electrode according to the present invention improves a thermal defect of the electrode due to a high-temperature baking process, prevents excessive loss of raw materials, and can manufacture aluminum electrodes of various sizes with area ranging from small to large at relatively low costs and by a simple process under atmospheric pressure.

The present disclosure provides a composite heat-dissipation substrate and a method of manufacturing the same. The composite heat-dissipation substrate includes a first ceramic layer having insulating properties, a second porous ceramic layer and a metal layer, wherein the first ceramic layer and the second ceramic layer are continuously connected to each other so as not to form an interface therebetween, and the metal layer is infiltrated into plural pores of the second ceramic layer to be coupled to the ceramic layers, whereby interfacial coupling force between the ceramic layers and the metal layer is very high, thereby providing significantly improved heat dissipation characteristics.

A porous molybdenum disilicide-based material prepared by preheating a preform consisting of size-controlled molybdenum (Mo) powder and content-controlled silicon (Si) powder and igniting the preform to initiate self-propagating high temperature synthesis, and a method for preparing the same, are disclosed. The method comprises the steps of a) mixing molybdenum (Mo) powder and silicon (Si) powder in the stoichiometric ratio of 1:2; b) molding the mixed powder into a preform; c) preheating the preform under inert atmosphere; and d) igniting the top end of the preheated perform. The porous molybdenum disilicide-based material can control its pore size by appropriately controlling the size of molybdenum (Mo) powder, the content of silicon (Si) powder and preheating condition. Therefore, since the pore size gradient of the porous material is possible to form, the porous material can be used for filters with improved dirt-holding capacity.
