Description

一种抗菌陶瓷材料
技术领域
本公开属于陶瓷材料技术领域，具体涉及一种抗菌陶瓷材料。
背景技术
陶瓷材料是工程材料中刚度最好、硬度最高的材料，其硬度大多在1500HV以上。传统陶瓷主要采用天然的岩石、矿物、粘土等材料做原料，而新型陶瓷则采用人工合成的高纯度无机化合物为原料，在严格控制的条件下经成型、烧结和其他处理而制成具有微细结晶组织的无机材料。新型陶瓷材料在性能上有其独特的优越性。在热和机械性能方面，有耐高温、隔热、高硬度、耐磨耗等；在电性能方面有绝缘性、压电性、半导体性、磁性等；在化学方面有催化、耐腐蚀、吸附等功能。陶瓷材料因其抗腐蚀等性能优越在日常生活中应用广泛，但是在在夏季细菌等微生物滋生的季节，即使保持卫生，也很难避免细菌的侵袭，如何制造一种抗菌陶瓷是目前所要解决的技术问题。
发明内容
本公开的目的是提供一种抗菌陶瓷材料，以达到提高陶瓷抗菌性能的目的。
为实现上述目的，技术方案如下：
