High-temperature-resistant light wave-transparent porous Al5BO9 ceramic material and preparation method thereof
The invention discloses a preparation method of a high-temperature-resistant light wave-transparent porous Al5BO9 ceramic material, which comprises the following steps: mixing Al2O3 powder and B2O3 powder to obtain mixed raw material powder; adding a dispersing agent into the mixed raw material powder to obtain slurry; sequentially carrying out ball milling, drying, grinding and sieving on the slurry to obtain powder; performing cold press molding on the powder to obtain a biscuit block; and sintering the biscuit block body to obtain the porous Al5BO9 ceramic. The invention also discloses the porous Al5BO9 ceramic material obtained by the preparation method, the density range is 1.20-2.00 g/cm < 3 >, the porosity range is 30-70%, and the porous Al5BO9 ceramic material is a porous boroaluminate ceramic material with low density, low thermal conductivity, low dielectric constant and high compression strength, and can be used in the field of high-temperature wave-transparent materials.
本发明公开了一种耐高温轻质透波多孔Al5BO9陶瓷材料的制备方法，包括将Al2O3粉和B2O3粉混合，得到混合原料粉；在混合原料粉中加入分散剂，得到浆料；对浆料依次进行球磨、干燥、研磨和过筛，得到粉料；利用粉料进行冷压成型，得到素坯块体；将素坯块体烧结后得到多孔Al5BO9陶瓷。本发明还公开了一种由上述制备方法得到的多孔Al5BO9陶瓷材料，密度范围为1.20g/cm3～2.00g/cm3，孔隙率范围为30％～70％，是一种低密度、低热导率、低介电常数、高压缩强度的多孔硼铝酸盐陶瓷材料，可用于高温透波材料领域。
