一种吸收高温二氧化碳的硅酸锂陶瓷材料及其制备方法
摘要：
本发明涉及一种吸收高温二氧化碳的硅酸锂陶瓷材料及其制备方法，其特征在于由以下重量百分比的原料制成：SiO212.41%～28.9%，Li2CO330.52%～71.1%，K2CO30～57.07%。其制备方法为：按上述配比将各原料混合，放入研钵中进行研磨，研磨后的原料放入高温电阻炉中进行高温煅烧，煅烧温度为600℃～1000℃，保温时间为0.5h～8h，即得到一种吸收高温二氧化碳的硅酸锂陶瓷材料合成钾掺杂硅酸锂陶瓷材料。本发明的材料可以对水泥窑，玻璃厂等尾气烟道中排放的大量高温二氧化碳进行直接吸收，与已有技术相比，本发明所制备的钾掺杂硅酸锂陶瓷可实现对二氧化碳更高的吸收效率，更易实现对二氧化碳的高利用率。
摘要（英）：

The invention relates to a lithium silicate ceramic material absorbing high-temperature carbon dioxide and a preparation method of the lithium silicate ceramic material absorbing high-temperature carbon dioxide. The lithium silicate ceramic material absorbing high-temperature carbon dioxide is characterized by comprising the raw materials by weight percent: 12.41-28.9% of SiO2, 30.52%-71.1% of Li2CO3 and 0-57.07% of K2CO3. The preparation method of the lithium silicate ceramic material absorbing high-temperature carbon dioxide comprises the following steps of: mixing the raw materials according to the proportion, putting in a mortar and grinding, putting the ground raw materials into a high-temperature resistor furnace, and calcining under high temperature of 600DEG C to 1000DEG C for 0.5h-8h to obtain the lithium silicate ceramic material absorbing high-temperature carbon dioxide, so that the potassium-doped lithium silicate ceramic material can be synthesized. The material provided by the invention can directly absorb a mass of high-temperature carbon dioxide discharged out by a tail gas fuel in the cement kiln, the glass factory and the like. Compared with the prior art, the potassium-doped lithium silicate ceramic prepared by the preparation method is higher in the carbon dioxide absorbing efficiency, and higher in the carbon dioxide use ratio.
