Honeycomb ceramic carrier with high porosity and large aperture and preparation method thereof
The invention relates to the technical field of honeycomb ceramic materials, in particular to a high-porosity large-aperture honeycomb ceramic carrier and a preparation method thereof. The honeycomb ceramic carrier is obtained by firing raw materials containing aluminum ash residues subjected to denitrification treatment, light calcined magnesium oxide powder and quartz powder. The aluminum ash subjected to denitrification treatment is high in aluminum content and contains magnesium oxide, aluminum oxide does not need to be added, the addition of magnesium oxide is reduced, the activity of aluminum oxide and magnesium oxide in the aluminum ash subjected to denitrification treatment is high, the sintering temperature is reduced, solid waste is consumed, environmental protection is facilitated, and the cost is low; the high-porosity large-aperture honeycomb ceramic carrier disclosed by the invention is particularly suitable for a ship engine, can meet the requirements of large catalyst amount, long service life and low cost, and has a good application prospect.
本发明涉及蜂窝陶瓷材料技术领域，具体而言，涉及一种高孔隙率大孔径的蜂窝陶瓷载体及其制备方法。该蜂窝陶瓷载体采用含有经过脱氮处理的铝灰渣、轻烧氧化镁镁粉以及石英粉的原料烧成得到。经过脱氮处理的铝灰渣铝含量高，同时含有氧化镁，不需要添加氧化铝，减少氧化镁的加入，经过脱氮处理的铝灰渣中氧化铝、氧化镁活性高，有利于降低烧成温度，消耗固废，有利于环境保护，成本低廉；本发明的高孔隙率大孔径蜂窝陶瓷载体，特别适用于船机发动机，能够满足催化剂量大、寿命要求高、成本低的要求，具有良好的应用前景。
