Foamed ceramic prepared from gold tailings and coal gangue and preparation method
The invention relates to the technical field of building materials, in particular to foamed ceramic prepared from gold tailings and coal gangue and a preparation method. The preparation method comprises the following steps of: by taking gold tailings and coal gangue as main raw materials and micro silicon powder, albite, silicon carbide micro powder, talc and calcite as auxiliary materials, carrying out ball milling, sieving and sintering to prepare the foamed ceramic with the average foam diameter of 1-3mm, the density of 350-600kg/m < 3 >, the compressive strength of 4.7-7.6 MPa and the heat conductivity coefficient of 0.049-0.062 W/(m.k). According to the invention, different wastes are compounded for use, and the synergistic and complementary effects among solid waste components are utilized, so that the foamed ceramic with excellent performance is prepared, and bulk utilization of solid wastes is realized.
本发明涉及建筑材料技术领域，尤其涉及一种利用黄金尾砂和煤矸石制备的发泡陶瓷及制备方法。本发明以黄金尾砂和煤矸石为主要原料，辅以微硅粉、钠长石、碳化硅微粉、滑石、方解石后，进行球磨，过筛，烧结，制备得到平均泡径1～3mm，密度350～600kg/m3，抗压强度4.7～7.6MPa，导热系数0.049～0.062W/(m﹒k)的发泡陶瓷。本发明通过将不同废弃物复合使用，利用固废组分之间的协同、互补的作用，制备出性能优良的发泡陶瓷，实现了固废的大宗化利用。
