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.
