优选的，其制备工艺包括以下步骤：
A、将硅酸锌、氮化铝、硅藻土、膨润土、氧化锆、碳化铬粉混合后加入粉碎机中粉碎，转速为1000转/分，粉碎时间为10min，之后过80目筛，得到混合物A；
B、在混合物A中加入羟乙基纤维素、硅微粉、白炭黑、纳米二氧化钛粉末、稳泡剂，混合后加入搅拌釜中搅拌，速率为300转/分，搅拌时间为25min，之后静置10min，得到混合物B；
C、在混合物B中加入硅烷偶联剂，充分混合后加入煅烧炉中煅烧，温度为800℃，时间为5min，之后缓慢冷却至室温，即得到陶瓷材料。
与现有技术相比，本发明的有益效果是：本发明制备工艺简单，制得的陶瓷材料具有高强度、高耐磨、耐高温的性能，使用寿命长；其中，添加的碳化铬粉、硅微粉、白炭黑，能够进一步提高陶瓷材料的耐磨性能；添加的纳米二氧化钛粉末，能够使陶瓷材料具有抗菌抑菌性能；经过试验得到，本发明制备的陶瓷材料耐高温达到1800℃，抗压强度达到80MPA。
