Production of corundum boats and crucibles used for metal melting and material analysis by casting method

Year: 2024

Type: article

Abstract: Technological features of producing corundum boats and crucibles used for metal melting and materials analysis by casting an aqueous slip in a plaster mould are presented. It is shown that to obtain high-density corundum ceramics by this method it is necessary to use aqueous slips with a maximum content of alumina up to 80 wt. %. The density of sintered products is significantly impacted by the initial size of alumina particles in the aqueous suspension. To increase the stability of the aqueous suspension and reduce its viscosity it is necessary to use a dispersing additive. The developed technology has produced corundum high-density and strong products in a form of boats and crucibles of different configurations and dimensions. Ill. 7. Ref. 11. Tab. 4.
