Fireclay Crucibles with Improved Properties for Assaying Ores
This paper explores the possibility of producing high-quality fireclay crucibles for assaying ores from the most high-grade local raw materials of Uzbekistan, kaolin of AKF-78 grade and fireclay obtained from this grade of kaolin. In order to increase physical and technical properties of fireclay crucibles, the masses were supplemented with pre-fired waste catalyst of Shurtan Gas Chemical Complex with 90.22% of Al2O3. The optimum mass with the 8% of alumina-containing waste withstands more than 11 – 13 melts without corroding, and the heat resistance of the samples increases up to eight heat cycles. Meanwhile, the amount of mullite formed after firing at 1420°C increases significantly. The development is aimed at utilizing local materials and recycling industrial waste, which is in line with the goals of sustainable development through waste reduction and efficient utilization of mineral resources.
