Method for preparing porous ceramic based on particle size and reaction activity control and porous ceramic
The invention discloses a method for preparing porous ceramic based on particle size and reaction activity control and the porous ceramic. The porous ceramic comprises a chemical structural expression as follows: xB2O3.ySiO2.uAl2O3.vN2O.wZO, N2O is Na2O or K2O, ZO is MgO, CaO, SrO, BaO or ZnO, x, y, u, v and w are molar ratios, 0.5<=x<= 2, 1<=y<=4, 0.1<=u<=1, 0.01<=v<= 0.1, and 0.01<=w<=0.1. The preparation method comprises the following steps: S1, weighing the raw materials according to the raw material composition, adding water, and carrying out ball milling for 1-3 hours to obtain a mixture; S2, separating out ceramic suspension slurry in the mixture obtained in S1, conducting drying to constant weight to obtain a dry sample, then smashing and grinding the dry sample to obtain a powdery material; and S3, carrying out powder granulation and molding on the powdery material obtained in S2, and conduting sintering at 800-950 DEG C for 2-3 hours to obtain the porous ceramic. According to the invention, through formula regulation and control and multi-ion doping, reaction activity is adjusted and generation of pores is controlled, and the porosity of the quartz glass powder is regulated and controlled under the control of the particle size of the quartz glass powder.
本发明公开了一种基于粒径和反应活性控制制备多孔陶瓷的方法及多孔陶瓷，多孔陶瓷包括化学结构表达式如下：xB2O3·ySiO2·uAl2O3·vN2O·wZO，其中，N2O为Na2O或K2O，ZO为MgO、CaO、SrO、BaO或ZnO，x、y、u、v、w为摩尔比，0.5≤x≤2，1≤y≤4，0.1≤u≤1，0.01≤v≤0.1，0.01≤w≤0.1。制备方法包括以下步骤：S1、按照原料组成分别称量各原料加水球磨1‑3h，得混合料；S2、分离出S1所得混合料中的陶瓷悬浮浆料，并烘干至恒重，获得干样，然后将干样粉碎研磨，获得粉状物料；S3、将S2所得粉状物料进行粉末造粒、成型，再在800‑950℃烧结2‑3h，即得。本发明通过配方的调控和多离子掺杂调整反应活性控制产生气孔，并在石英玻璃粉的粒径控制下对其孔隙率进行调控。
