Popis:	The objective of this work is to develop a manufacturing method for porous SiO2. Porous SiO2 was fabricated by decarburization after sintered at 1472K with carbon particles. Porosity of C20SiO2 (added carbon particles of 20vol%), C40SiO2 (added carbon particles of 40vol%), C60SiO2 (added carbon particles of 60vol%) and C80SiO2 (added carbon particles of 80vol%) were 20.4 « 0.4, 40.5 « 0.4, 60.6 « 0.3, and 80.7 « 0.3vol%, respectively. It is to say that the porosity of the porous SiO2 could be controlled by less than «1% of the amount of carbon particles. In addition, pore size of porous SiO2 could be controlled by the size of the carbon particles. Furthermore, pore-size of the porous SiO2 depends on the size of carbon particles instead of the quantity of the carbon particles. Decarburization processing method is a simple and economical manufacturing method to controlled porosity and pore size of porous SiO2. [doi:10.2320/matertrans.M2012181]
