Abstract
The invention relates to a preparation method of a ZrN-SiAlON-SiC-C complex-phase fireproof material, and belongs to the field of fireproof materials. Bauxite and zirconite are served as raw materialsto prepare ZrN-SiAlON fireproof powder, a sugarcane solution is served as a binding agent to combine 120-mesh SiC and 325-mesh SiC, the material is formed and subjected to thermal treatment at the temperature of 1500 DEG C to prepare the ZrN-SiAlON-SiC-C fireproof material. When the mass ratio of the ZrN-SiAlON fireproof powder to 120-mesh SiC to 325-mesh SiC is 2 to 4 to 4, the breaking strengthof the fireproof material is 3.53 MPa, the apparent porosity is 41.10%, and the volume density is 1.76g/cm<3>. When the mass ratio is 3 to 3.5 to 3.5, the breaking strength of the fireproof materialis 4.32 MPa, the apparent porosity is 45.79%, and the volume density is 1.57g/cm<3>. When the mass ratio is 4 to 2 to 2, the breaking strength of the fireproof material is 4.39 MPa, the apparent porosity is 53.23%, and the volume density is 1.36g/cm<3>. When the mass ratio is 4 to 2 to 2, the breaking strength of the fireproof material is 4.25 MPa, the apparent porosity is 50.61%, and the volume density is 1.41g/cm<3>. The preparation technology related to the invention can be an effective high-technology and low-cost route to prepare high-performance ZrN-SiAlON-SiC-C fireproof material products.
