用粉煤灰和磷酸二氢铝制备轻质多孔陶瓷的方法
摘要：
用粉煤灰和磷酸二氢铝制备轻质多孔陶瓷的方法，其特征在于采用以下步骤：（1）把粉煤灰，磷酸二氢铝粉末，熔块粉末按比例进行干混；（2）造粒、成型，制得坯体；（3）在70℃干燥坯体5小时后，在大气气氛下以5℃/min的速度加热升温到150℃并保温2小时，再以10‑20℃/min的速度加热升温到380℃并保温1个小时，然后以1℃/min的速度加热升温到680℃并保温2小时，最后以5℃/min的速度加热升温到1150℃并保温2个小时，随后自然冷却到室温，即制得轻质多孔陶瓷。
摘要（英）：

The invention relates to a method for preparing lightweight porous ceramics with fly ash and aluminum dihydrogen phosphate. The method is characterized in comprising the following steps: (1) fly ash, aluminum dihydrogen phosphate powder and frit powder are subjected to dry mixing according to a certain ratio; (2) granulation and molding are carried out, such that a blank is prepared; (3) the blank is dried for 5h under a temperature of 70 DEG C, and is then heated to a temperature of 150 DEG C in an air atmosphere with a speed of 5 DEG C/min; the temperature is maintained for 2h; the blank is heated to a temperature of 380 DEG C with a speed of 10-20 DEG C/min, and the temperature is maintained for 1h; the blank is heated to a temperature of 680 DEG C with a speed of 1 DEG C/min, and the temperature is maintained for 2h; the blank is heated to a temperature of 1150 DEG C with a speed of 5 DEG C/min, and the temperature is maintained for 2h; and the product is naturally cooled to room temperature, such that the lightweight porous ceramics is obtained.
