The data on the melting of zircon with the addition of glassforming oxides are given. The structure of the synthesized materials is represented by baddeleite and glass phase, which determine the operational characteristics of the refractory. Corrosion tests of samples of melted zircon in molten aluminum alloys showed their zero wettability and minimal corrosion. The material with an less than 2 % SiO2 was obtained when melted zircon was treated with a solution of 10 % HF. The threefold decrease in the silica content in the melting product was observed in electric arc furnace with carbothermic melting of zircon.

This article discusses research on using power ultrasound for degassing of molten aluminum alloys. At least three types of technique have been developed for ultrasonic degassing. The type deals with degassing using power ultrasound alone. Degassing in a small melt can be achieved within a few minutes of ultrasonic vibration. The second type is ultrasound assisted vacuum degassing. A combination of vacuum and power ultrasound makes degassing much complete and fast. The third type is ultrasound assisted lance degassing. Ultrasonic vibration is used to break up the large argon or nitrogen bubbles into much smaller ones, resulting in an increased efficiency of degassing of aluminum melt. The benefits of ultrasonic degassing include: no moving/rotation part in the degassing system; less use of argon and no use of chlorine; and less amount of dross formation during degassing. Furthermore, trace elements such as Na and Li can be removed using ultrasonic degassing. Keywords: Aluminum alloys, degassing, porosity, and power ultrasound
