Abstract: Research was conducted on the effects of varying power and treatment temperature on molten GW103K magnesium purification by ultrasound. Low temperature and high power levels both adversely affected ultrasonic purification efficiency. An ultrasonic power of 200 W for 60 sec at a temperature of 680°C provided good purification. Ultrasonic power of 160 W for 60 sec at either 710 or 730°C provided even better purification. Conductivity decreased as ingot inclusions increased and can be used as an indicator of the level of ingot purification.
