Abstract

The invention belongs to the technical field of building materials, and discloses a rare earth oxide reinforced and toughened ceramic rock plate and a preparation method thereof, the rock plate comprises the following raw materials by mass: 30-45 parts of kaolin, 10-35 parts of bauxite, 15-25 parts of feldspar, 0-5 parts of talc, 15-25 parts of quartz, and 0.1-10 parts of rare earth oxide. According to the rare earth oxide reinforced and toughened ceramic rock plate, rare earth oxides (yttrium oxide, lanthanum oxide, cerium oxide, praseodymium oxide, neodymium oxide, samarium oxide and the like) and rock plate matrix powder are fully mixed, the rock plate is prepared through granulation, pressing and sintering, the bending strength and toughness of the rock plate are remarkably improved, and compared with the rock plate without the rare earth oxides, the bending strength of the obtained rock plate is increased by 45% or above.

Description

technical field

[0001] The invention relates to the technical field of building materials, in particular to a rare earth oxide reinforced and toughened ceramic rock plate and a preparation method thereof. Background technique

[0002] Today in the 21st century, energy and environmental issues have become prominent issues restricting the sustainable development of human society. Improving energy utilization efficiency and optimizing the industrial structure of all parties has become a necessary choice to promote the healthy development of society.

[0003] In response to the restrictions on the thickness of ceramic tile materials in national standards, architectural ceramic materials are developing towards lightweight, thin and environmentally friendly new decorative materials, which is conducive to eliminating backward production capacity in the industrial structure, optimizing production capacity structure, and conforming to green development. idea. While making architect...
