Porous ceramic material pore-forming agent and preparation method thereof
The invention discloses a porous ceramic material pore-forming agent and a preparation method thereof, the raw material is rice husk, and the raw material contains 27-28.5 wt% of carbon, 65.9-67.5 wt% of silicon dioxide, 2.1-2.3 wt% of calcium chloride, 0.1-0.15 wt% of iron trichloride and 3.2-3.4 wt% of potassium chloride. According to the preparation method, natural substance rice husks are subjected to high-temperature treatment to form carbide, and the formed carbide is granulated after being crushed and sieved to form pore-forming agent particles. Compared with an organic pore-forming additive and an inorganic pore-forming additive, the pore-forming additive has the characteristics of controllable shape, no adverse residue after sintering and the like.
本发明公开了一种多孔陶瓷材料造孔剂及其制备方法，其原料为稻谷壳，其中含有碳27‑28.5wt％、二氧化硅65.9‑67.5wt％、氯化钙2.1‑2.3wt％、三氯化二铁0.1‑0.15wt％和氯化钾3.2‑3.4wt％。本发明通过对天然物质稻谷壳进行高温处理，形成碳化物，经破碎和过筛后，对所形成的碳化物进行造粒，形成造孔剂颗粒。本发明相比于有机造孔添加剂和无机造孔添加剂具有形状可控，烧结后无不良残留等特点。
