A lightweight high-strength ceramic particle. The raw materials comprise a solid raw material and an activator, the weight parts thereof being respectively 100 parts for the solid material, and 1-15 parts for the activator. The solid raw material comprises: 100 parts of fly ash, 6-18 parts of high-alumina fly ash, bauxite, and red mud, 1-5 parts of silica fume, 0.1-3 parts of a surfactant, 6-24 parts of a plasticizer. The activator comprises 5-20 parts of an alkali metal hydroxide, and 80-95 parts of an alkali metal silicate. Prepared ceramic particle products have a density level of 700‑1100 kg/m 3 , a cylinder compressive strength of 10‑20 MPa, and are not easily damaged. |
