Embodiment 1
[0034] A rare earth oxide reinforced and toughened ceramic rock plate, comprising the following raw materials in parts by mass: 39 parts of kaolin, 19 parts of bauxite, 20 parts of feldspar, 2 parts of talc, 16 parts of quartz and 4 parts of yttrium oxide; The purity of yttrium is ≥99.5%, and the particle size is 6 μm. The preparation method of the slate is as follows:
[0035] S1: Add water to kaolin, bauxite, feldspar, talc, quartz and yttrium oxide mixture, ball mill and mix for 10 hours to prepare a mixed slurry with a solid content of 55%;
[0036] S2: The mixed slurry is spray-dried and granulated to obtain a spherical granular powder with certain fluidity and sieved to obtain a granular powder with a particle size distribution of 40%≤30 mesh≤80%, stale for 2 days , to obtain green powder with a moisture content of 7%;
[0037] S3: Pressing the obtained green body powder into a press to obtain a green body and drying;
[0038] S4: Treat the surface of the dried green b...
