The invention discloses a method for preparing porous silicon carbide ceramic through reactive sintering and micro-oxidation treatment. The method comprises the following steps: firstly ball-milling a certain amount of mesocarbon microbeads and silica powder to obtain mixed powder, secondly dry-pressing the mixed powder at room temperature to prepare a green body, and finally carrying out high-temperature reactive sintering under the condition of micro-oxidation treatment, thus obtaining the porous silicon carbide ceramic. The method has the advantages that plenty of silicon carbide whiskers are generated in situ by adopting micro-oxidation treatment; meanwhile, an SiO2 glass phase is generated, thus promoting sintering and forming sintering necks among silicon carbide particles; the method is simple to operate and has high production efficiency; and the porous silicon carbide ceramic prepared by adopting the method is uniform in pore size distribution, has high bending strength and has strength of 176MPa when the porosity is 32%.
