| description | The invention relates to a preparation method of a thermal shock resistant and antioxidant Si3N4 combined SiC refractory material. According to the technical scheme, silicon carbide and molybdenum disilicide particles with the particle sizes of 1-3 mm and 0-1 mm are used as aggregates, silicon carbide fine powder, molybdenum disilicide fine powder and metal silicon powder with the particle sizes smaller than 0.064 microns are used as matrixes, and water-soluble resin is used as a binding agent. The preparation method comprises the following steps: taking proper contents of the raw materials, uniformly mixing the aggregate and the binding agent in an edge runner, then adding the uniformly mixed fine powder of the raw materials, uniformly stirring, and properly bundling. The preparation method comprises the following steps: mixing Si3N4 with SiC, then carrying out mechanical pressing molding on a friction brick press, firstly drying a green body for 24 hours at 110 DEG C, and carrying out heat preservation for |
