The invention provides a high - strength, multi - morphological Al 2 O 3 particle/Al 2 O 3 fiber composite ceramic sheet and a preparation method. Manganese oxide, cement soil, potassium feldspar, kaolin, black talc, ball soil, xenotime, carboxymethyl cellulose and sodium tripolyphosphate are uniformly mixed, and then crushed, ball milled and pulped to obtain pulp material precursor B; the prepared slurry precursor B, Al 2 O 3 fiber C and KH550 solution are mixed uniformly to obtain green powder D; High-strength, multi-morphological Al 2 O 3 particle/Al 2 O 3 fiber composite ceramic sheet. In the invention, the one-dimensional Al 2 O 3 fibrous body, the multi-morphological Al 2 O 3 particles and the ceramic matrix powder are closely combined, and the prepared large-scale ceramic thin plate has excellent mechanical properties. In addition, the production process is simple, the production cycle is short, and it is easy to combine with the current traditional ceramic thin plate production process, and the potential commercial market is broad. |
