In the highly refractory zirconate product process, the most difficult is synthesis and sintering. The zirconium oxide densified material has a large linear shrinkage during sintering and is preferably prepared in two stages, ie, pre-synthesized at 1400e and then fired at 1700e. During synthesis, poor loosening also occurs due to the diffusion of cerium oxide. It can be considered that in the case of producing a porous material, this effect would rather be beneficial because the shrinkage rate would be compensated. Not only that, when producing porous refractory materials, it is also possible to combine synthesis with sintering. Another difficulty in the process is the formation of porous and strong structures. For the aluminophosphate binder-based composites, the industrial ZrO2 has the best effect. In short, the cast material has a high porosity and can be used as a heat-insulating material. In the case of using orthophosphoric acid as a mixed liquid, a higher strength (compared to the use of an aluminophosphate binder) strength material was produced. The use of carbon fibers and aramid fibers as reinforcing materials does not increase the strength of the ceramic material because the interaction between the fibers and the matrix is ​​not large. After treating the carbon fibers with various slurries, it was determined that Na2SiF6 can increase the interaction between the fibers and the matrix, so that the material strength is increased. Reinforcing ceramics with micro-fibrous ZrO2 can increase its strength. As the cerium-containing component, cerium carbonate is used, and as the zirconium-containing component, zirconium dioxide and oblique zirconium ore powder are used. Although relatively pure zirconium dioxide can guarantee the excellent performance of synthetic zirconate, the significance of zirconium ore fines is that it is inexpensive and suitable for industrial production of refractory materials. The initial powders of cerium carbonate and zirconium oxide have a size suitable for synthesis (essentially less than 3Lm), and the zirconium ore powder is different from this and has a larger particle size and must be ground again during synthesis. By vibrating and grinding, it reaches the corresponding particle size. The material of the dense sintered layer of refractory material was pressed and formed under the pressure of 100 MPa by the steel mold, and different porosity layers were formed by tamping. Pre-expanded polystyrene particles of different bulk densities were introduced as incineration additives to construct and adjust the pore structure.
