Abstract ZrO2 hollow-fiber bricks are a type of thermal-insulation product with low density and thermal conductivity. ZrO2 hollow-fiber bricks made with Zr-sol as the high-temperature binder have poor strength; therefore, it is necessary to find a binder that can overcome these challenges. Rice husk contains a large concentration of amorphous SiO2, because of which it can be used as a binder for ZrO2 hollow-fiber bricks. After treatment, rice husk powder was added to the ZrO2 hollow fibers as a high-temperature binder, which formed ZrO2 hollow-fiber bricks after sintering. The densities and thermal conductivities of these ZrO2 bricks prepared at 1300 °C were unaffected by the rice husk-derived binder, while the compressive strengths increased by 285% compared with that of the Zr-sol binder.

稻壳粉作为粘结剂对ZrO2中空纤维耐火砖力学性能和热性能的影响

摘要 ZrO2中空纤维砖是一种低密度、低导热的保温产品。以Zr-sol为高温粘结剂制成的ZrO2中空纤维砖强度较差；因此，有必要找到一种能够克服这些挑战的粘合剂。稻壳中含有大量无定形SiO2，因此可用作ZrO2中空纤维砖的粘合剂。处理后，在ZrO2中空纤维中加入稻壳粉作为高温粘结剂，烧结后形成ZrO2中空纤维砖。这些在 1300 °C 下制备的 ZrO2 砖的密度和热导率不受稻壳粘合剂的影响，而抗压强度与 Zr-sol 粘合剂相比提高了 285%。
