Abstract

The invention discloses a high-strength, strong-toughness foamed hollow ceramic material, which comprises the following raw materials in proportions by weight: 70-80 parts of a base material, 15-20 parts of a foaming material, 10-15 parts of a colorant and 5 parts of an additive ‑10 servings. The high-strength and tough foam hollow ceramic material is mixed with additives, matrix materials, foam materials and colorants to process foam ceramics with high strength and high toughness. Various raw materials are easy to obtain and low in cost. The preparation method Simple.

Description

technical field [0001] The invention relates to the technical field of foamed ceramic materials, in particular to a foamed hollow ceramic material with high strength and toughness. Background technique [0002] The development of foamed ceramic materials began in the 1970s and is a porous material with high temperature properties. The pore size varies from nanometer to micrometer, the porosity is between 20% and 95%, and the service temperature is normal temperature to 1600°C. [0003] Foamed ceramics can generally be divided into two categories, namely open-cell (reticular) ceramic materials and closed-cell ceramic materials, depending on whether the individual cells have solid walls or not. If the solids that form the foam are only contained in the pore edges, it is called an open-cell ceramic material, and the pores are interconnected; if there is a solid wall, the foam is called a closed-cell ceramic material, and the pores are continuous. The ceramic substrates are se...
