Abstract
本发明涉及一种多功能性陶瓷材料及其制备方法,属于陶瓷材料技术领域。该多功能性陶瓷材料包括如下组分:功能材料III、煤系高岭土、钙基膨润土、蛇纹石。在制备功能材料III时,以矿床地处阴山北麓东端,内蒙古中部南缘的特定花岗斑岩为原料,首先通过花岗斑岩相互碰撞,控制碰撞条件,使不同元素晶体能够层层破壁剥离和分离,接着根据不同的元素晶体比重调节水力分级机参数,进行水离分级富集,即可。由于功能材料III中存在稀土元素,能降低多功能性陶瓷材料的熔点,使坯料孔隙率降低,致密性提高,阻碍其他离子迁移,降低晶界迁移的速率,抑制晶粒生长,从而有利于致密性结构的形成,使玻璃相的强度得到提高,最终达到改善陶瓷力学性能的目,最终制备的产品吸水率低,抗冲击性强。

技术领域
本发明属于陶瓷材料技术领域,具体涉及一种多功能性陶瓷材料及其制备方法。
背景技术
国内市场所见的以稀土元素所生产的功能性陶瓷制品,烧制后的坯体颜色几乎以浅黄、浅青、不透明为主,目前市场所出现的功能陶瓷从定义讲应称之为陶器或者炻器,国内投放市场批量生产的陶瓷产品几乎全部采用添加稀土尾矿或者电气石等材料,由于这些材料富含有多种金属元素,而这些金属元素在生产工艺过程中又无法去除,导致无法生产出高品质、白、透亮的瓷器。
陶瓷原料是发展陶瓷工业最基础的物质条件,而我国陶瓷工业遍及国内各个地区,且都建立在“因地制宜、就地取材、量材施用”的前提下进行,由于各地原料性质不同,所生产的产品品质也各有千秋,随着时代的进步,也随着生活水平的提高,陶瓷工业的发展势必会走向高品质、精加工、标准化的发展之路。
