Description

一种利用晶须纤维增韧的高韧陶土
技术领域
本发明属于陶瓷材料技术领域，尤其涉及一种利用晶须纤维增韧的高韧陶土。
背景技术
陶器，是用黏土或陶土经捏制成形后烧制而成的器具。陶器历史悠久，在新石器时代就已初见简单粗糙的陶器。陶器在古代作为一种生活用品，在现在一般作为工艺品收藏。
但为了保留传统的风味，也有部分场合适合使用陶器容器的，如泡茶。常见的泡茶用具有紫砂壶，紫砂壶也属于陶器的一种，但是由于原料缺乏和市场竞争的结果，目前紫砂壶价格居高不下。实际上采用高岭石等普通陶土的泡茶效果能与紫砂相媲美，但是普通陶土所制成的陶器，特别是烧水陶壶等需要接受炭火烘烤的陶器，其本身对陶器的韧性有一定的要求，然而现在的陶器韧性不足，容易开裂，导致使用寿命大大下降，也影响了使用效果和陶器的外观。
发明内容
基于现有技术存在上述问题，本发明提供一种利用晶须纤维增韧的高韧陶土，其在常规的陶土配方中添加了碳化硅纤维，通过碳化硅纤维增加了陶土的韧性，提高了其所制造出的陶器的韧度。同时还添加了烧结助剂，提高了陶土的致密度，进一步增强陶土的韧性。
本发明通过以下技术方案达到目的：
一种利用晶须纤维增韧的高韧陶土，其由以下组成成分按一定的质量分数组成：高岭石30-40份、石英25-35份、水白云母10-20份、蒙脱石20-30份、碳化硅纤维10-15份、烧结助剂4-8份、硼化锆10-16份。
优选地，其由以下组成成分按一定的质量分数组成：高岭石34-36份、石英28-32份、水白云母14-18份、蒙脱石24-26份、碳化硅纤维12-14份、烧结助剂5-7份、硼化锆12-14份。
优选地，其由以下组成成分按一定的质量分数组成：高岭石35份、石英30份、水白云母16份、蒙脱石25份、碳化硅纤维13份、烧结助剂6份、硼化锆13份。
其中，所述的烧结助剂是钇铝石榴石。
其中，所述的碳化硅纤维是直径为16-18μm，长度为2-4mm的碳化硅纤维。
本发明具有的有益效果：通过碳化硅纤维增加了陶土的韧性，碳化硅纤维在陶土中能实现桥联增韧，并且使裂纹的方向在纤维的作用下会发生偏离，增加了裂纹延伸所需能量，同时碳化硅纤维还能通过拔出效应提高其所制造出的陶器的韧度。另外，还添加了烧结助剂，提高了陶土的致密度和保证了碳化硅的增韧性能，进一步增强陶土的韧性。
