Abstract

A ceramic material based on clay with sludge waste from the Tuvacobalt Plant is obtained. The highest strength of the samples is observed at a charge firing temperature of 900°C, which is possibly due to the presence in the sample of refractory materials: quartz, plagioclase (albite), akermanite, and clinoenstatite, forming strong binding structures. By mixing the waste with the clay, the arsenic content in the samples is reduced up to four times compared to the sludge. It is established that arsenic is not washed out from the ceramic samples obtained by firing a mixture of clay with sludge.

处理污泥废料以生产陶瓷材料

我们获得了一种基于粘土和图瓦钴工厂污泥废料的陶瓷材料。在装料烧成温度为 900°C 时，样品的强度最高，这可能是由于样品中存在耐火材料：石英、斜长石（白云石）、赤铁矿和褐铁矿，形成了强大的结合结构。通过将废物与粘土混合，样品中的砷含量比污泥减少了四倍。通过将粘土与污泥混合烧制得到的陶瓷样品中的砷不会被洗掉。
