Foaming ceramic synthesized from fly ash and lithium slag and preparation method thereof
The preparation method comprises the following steps: uniformly mixing the fly ash, the lithium slag, talc, albite, potassium feldspar and a foaming agent, and carrying out wet milling by using a ball mill to prepare slurry; performing spray granulation to obtain powder particles, and performing calcination treatment; and cooling to obtain the foamed ceramic material. The preparation method has the beneficial effects that the lithium slag and the fly ash are compounded according to a certain proportion for use, and a molten mass formed by the lithium slag at a relatively low temperature can exert migration and permeation effects to spontaneously arrange the longitudinal height of the raw materials, so that the surface tension of the molten mass at a final firing temperature has certain difference in different areas; due to the existence of the difference, the resistance change of pores in the foamed ceramic in the aspects of formation, growth and distribution is eliminated, and uniform distribution of a longitudinal structure is realized; large-dosage and high-value application of the fly ash and the lithium slag can be achieved at the same time, and the problem of environmental pollution caused by fly ash accumulation and lithium slag storage is effectively solved.
本发明涉及一种利用粉煤灰和锂渣合成的发泡陶瓷及其制备方法，包括步骤：将粉煤灰、锂渣、滑石、钠长石、钾长石和发泡剂均匀混合，利用球磨机湿磨制成浆料；喷雾造粒，得到粉体颗粒，煅烧处理；冷却得到发泡陶瓷材料。本发明的有益效果是：将锂渣与粉煤灰按一定配比复配使用，锂渣在较低温度下形成的熔融体可发挥迁移和渗透作用进行原料纵向高度的自发排列，导致最终烧成温度下熔融体的表面张力在不同区域具备一定的差异性；该差异性的存在有利于消除发泡陶瓷中气孔在形成、生长与分布方面的阻力变化，实现纵向结构的均匀分布；可同时实现粉煤灰与锂渣的大掺量高值化应用，有效解决因粉煤灰堆积和锂渣存放导致的环境污染问题。
