摘要/Abstract

摘要： 以煤矸石和废玻璃为主要原料制备泡沫陶瓷,研究了煅烧温度和Na₃PO₄添加量对泡沫陶瓷的物相结构、显气孔率、抗压强度及表观密度等的影响。结果表明:陶瓷样品的线性膨胀率随煅烧温度的升高而逐渐增加,表观密度随煅烧温度的升高而逐渐降低;提高煅烧温度或Na₃PO₄添加量使泡沫陶瓷的平均孔径、显气孔率逐渐增加,抗压强度下降,表观密度呈不同的变化趋势,但未明显影响晶体结构。通过优化制备条件发现,当Na₃PO₄添加量为3%(质量分数)、煅烧温度为1 140 ℃时,样品孔径均匀,平均孔径为0.92 mm,抗压强度达到4.72 MPa,表观密度为0.69 g/cm³。本研究的煤矸石基泡沫陶瓷制备工艺简单,成本低,为煤矸石资源化利用提供了一条可行途径。

Abstract: Coal gangue and waste glass were used as main raw materials to prepare foamed ceramics. The effects of calcination temperature and content of Na₃PO₄ on phase structure, apparent porosity, compressive strength and apparent density of foamed ceramics were studied. The results show that, as the calcination temperature increases, the linear expansion rate of foamed ceramics samples gradually increases, while the apparent density gradually decreases. The average pore diameter and apparent porosity of foamed ceramics gradually increase and the compressive strength decreases as the calcination temperature or the Na₃PO₄ content increases, while the apparent density shows different trends and the crystallite structure of the sample changes very slightly. By optimizing the preparation conditions, it is found that when the content of Na₃PO₄ is 3% (mass fraction) at the calcination temperature of 1 140 ℃, the prepared foamed ceramics exhibits uniform pore structure with the average pore diameter of 0.92 mm, the compressive strength reaches as high as 4.72 MPa, and the apparent density achieves 0.69 g/cm³. The preparation process of foamed ceramics based on coal gangue is simple and the cost is low, which provides a feasible way for the utilization of coal gangue resources.

Key words: foamed ceramics, coal gangue, waste glass, calcination temperature, Na₃PO₄, pore structure
