Embodiment 1
[0017] Weigh separately w (La 2 o 3 ) ≥ 99%, 1 kg of lanthanum oxide fine powder with particle size less than or equal to 60 μm, w (Al 2 o 3 +MgO)=99.0%, particle size ≤0.1mm and fused magnesia-aluminum spinel fine powder with 95% spinel phase, 24kg, mixed for 6h; then weighed w (SiC)=97.0%, 75kg of silicon carbide particles with a particle size greater than 0.1mm and less than or equal to 5mm, mixed with 4kg of resin binder in a roller sand mixer, added the matrix mixed in the previous stage, stirred and mixed evenly, and formed With viscous sand-like material, the material is trapped for 24 hours; after the sand-like material is trapped, it is formed into a green body in a steel mold on a 630 T friction brick press; it is dried in three steps: natural drying for 12 hours, forced drying at 70°C for 12 hours, and 150 ℃ forced drying for 6 hours; finally put the dried green body into a sagger filled with graphite powder and embed carbon for treatment, and burn it in a resi...

[0019] Weigh separately w (La 2 o 3 ) ≥ 99%, 1 kg of lanthanum oxide fine powder with particle size less than or equal to 60 μm, w (Al 2 o 3 +MgO)=99.0%, particle size ≤0.1mm and fused magnesia-aluminum spinel fine powder with 95% spinel phase, 24kg, mixed for 6h; then weighed w (SiC)=97.0%, 75kg of silicon carbide particles with a particle size greater than 0.1mm and less than or equal to 5mm, mixed with 4kg of resin binder in a roller sand mixer, added the matrix mixed in the previous stage, stirred and mixed evenly, and formed With viscous sand-like material, the material is trapped for 24 hours; after the sand-like material is trapped, it is formed into a green body in a steel mold on a 630 T friction brick press; it is dried in three steps: natural drying for 12 hours, forced drying at 70°C for 12 hours, and 150 ℃ forced drying for 6 hours; finally put the dried green body into a sagger filled with graphite powder for carbon treatment, and burn it in a resistance fur...
Embodiment 3
[0021] Weigh separately w (Y 2 o 3 ) ≥ 99%, 5 kg of yttrium oxide fine powder with particle size less than or equal to 60 μm, w (Al 2 o 3 +CaO)=99.0%, particle size ≤0.1mm and calcium hexaaluminate phase of 95% calcium hexaaluminate powder 20kg, mixed for 6h; then weighed w (SiC)=97.0%, 75kg of silicon carbide particles with a particle size greater than 0.1mm and less than or equal to 5mm, mixed with 4kg of resin binder in a roller sand mixer, then added the fine powder mixed in the previous stage, and stirred to mix evenly. A viscous sand-like material is formed, and the material is trapped for 24 hours; after the sand-like material is trapped, it is formed into a green body in a steel mold on a 630 T friction brick press; it is dried in three steps: natural drying for 12 hours, forced drying at 70°C for 12 hours, Forced drying at 150°C for 6 hours; then put the dried green body into a sagger filled with graphite powder for carbon treatment, and burn it in a resistance f...
