| titleOfInvention | Porous corundum-mullite ceramic with nano-pore diameter and preparation method thereof |
| abstract | The invention relates to a porous corundum-mullite ceramic with a nano-aperture and a preparation method thereof. The technical scheme is as follows: and heating the aluminum hydroxide fine powder to 280-450 ℃ and 800-1200 ℃ in sequence, and respectively preserving heat to obtain the high-porosity aluminum oxide powder. The method comprises the following steps of mixing 70-90 wt% of high-porosity alumina powder, 9-29 wt% of silica sol and 1-10 wt% of silica micropowder, placing the high-porosity alumina powder in a vacuum mixer, vacuumizing to below 2.0kPa, adding the silica sol and the silica micropowder into the vacuum mixer, and stirring to obtain a mixture. And (3) preserving the heat of the mixture at 110-220 ℃, cooling, performing mechanical compression molding, drying, sequentially heating to 800-1100 ℃ and 1400-1600 ℃, and respectively preserving the heat to obtain the porous corundum-mullite ceramic with the nano pore diameter. The pore diameter of the pores of the product prepared by the invention is nano-scale, and the product has the characteristics of low air permeability, low thermal conductivity, good volume stability and high strength. |
