Iron-stabilized selenium-enriched ceramic material and preparation method thereof
The invention belongs to the technical field of ceramic materials, and particularly discloses an iron-stabilized selenium-rich ceramic material and a preparation method thereof, the iron-stabilized selenium-rich ceramic material mainly comprises kaolin, a selenium source and an iron source, the uniformly mixed selenium-rich pottery clay material is molded through a conventional pottery making process, dried, is kept for 1-6h in a reducing atmosphere or other inert atmospheres at the temperature of 800-1200 DEG C, and then sintered to prepare a selenium-rich pottery sample, and the selenium content and the selenium dissolution amount of the selenium-rich pottery sample is detected after soaking in water to obtain the iron-stabilized selenium-rich ceramic material. The content of iron is 1wt%-15wt%, and the content of selenium is 10-200ppm. The preparation method disclosed by the invention is beneficial to sintering the selenium-rich ceramic at high temperature and enabling selenium to stably exist in the ceramic, and when the selenium-rich ceramic is used, a proper amount of selenium can be dissolved out when the selenium-rich ceramic is soaked in water or water containing food. According to the material and the preparation method thereof, the iron source is added, so that the sintering temperature of the selenium-rich ceramic can be increased, the selenium content in the selenium-rich ceramic can be stabilized, the selenium release amount can be controlled, and the effect of safely and stably releasing selenium for a long time is achieved.
本发明属于陶瓷材料技术领域，具体公开了一种铁稳定富硒陶瓷材料及其制备方法，主要由高岭土、硒源和铁源组成，混合均匀后的富硒陶土材料通过常规的制陶工艺成型、烘干并在还原性气氛或其他惰性气氛下于800‑1200℃保温1‑6h后烧结制备得到富硒陶样品，对其硒含量及其在水种浸泡后的硒溶出量进行检测，得到铁稳定富硒陶瓷材料；其中铁含量为1wt％‑15wt％，硒含量为10‑200ppm。本发明的制备方法有利于富硒陶瓷在高温下烧结并且使硒稳定存在于陶瓷中，并且该富硒陶瓷在使用时能够在水或者含有食物的水中浸泡时溶出适量的硒。本发明的特点是通过加入铁源能够提高富硒陶瓷的烧结温度和稳定其中硒的含量，同时能够控制硒的释放量，从而达到安全、稳定和长期释放硒的作用。
