摘要

以油棕木粉为成孔剂，以聚乙烯醇和粘土为基材制备多孔陶瓷。多孔陶瓷是由80%的粘土，15%的聚乙烯醇和5%的油棕木粉组成的。棕榈油木粉的颗粒大小是多种多样的，即100目、150目和200目。烧结过程在1000℃的温度下进行，保温时间为2小时。用EDX分析测定了粘土的化学成分。对制备的多孔陶瓷进行了孔隙率和硬度测试。结果表明，油棕木粉的粒度对陶瓷的硬度和孔隙率有很大影响。油棕颗粒的孔径越大(粒径越小)，陶瓷的硬度越高，但孔隙度却越来越小。

Effect of Particle Size from Oil Palm Wood Powder as Pore Forming Agent on Porosity and Hardness of Porous Ceramics based on Clay and Polyvinyl Alcohol

: Preparation of porous ceramics based on polyvinyl alcohol and clay has been carried out by using oil palm wood powder as a pore forming agent. Porous ceramics are made with a composition: 80% clay, 15% PVA and 5% oil palm wood powder. The size of the particles of palm oil wood powder is varied, namely 100, 150 and 200 mesh. The sintering process is carried out at a temperature of 1000 °C with a holding time of 2 hours. The chemical composition of clay is determined by EDX analysis. The porous ceramics produced were tested for porosity and hardness. The result shows that the particle size of oil palm wood powder is very influential on the hardness and porosity of the ceramic. The larger the mesh size of the particles of oil palm (the smaller the particle size) the higher the hardness of the ceramic, but the porosity is getting smaller.
