Sialon Ceramics: ultrasonic degassing in molten glass

Sialon Ceramics Ltd and Akve Arc ltrasonics Sarl announced a breakthrough in ultrasonic molten gas technology that can reduce energy costs by 20 percent and lower the environmental impact of glass manufacturing. The process uses a new ultrasonic generator and a proprietary ceramic sonotrode to treat large volumes of high viscosity molten glass at temperatures []

Ultrasonic Degassing and Defoaming of Liquids

ultrasonic degassing of oil (5 seconds) Even in still water, e.g. after 24 hours, sonication will generate small bubbles in the clear water. These bubbles fill with dissolved gas, that migrates into the bubbles. Consequently the bubbles grow and move up. The degassing

Ultrasonic Degassing of Molten Aluminum under

Ultrasonic degassing, an environmentally clean and cheap technique, is an efficient way of degassing in a static volume melt. Vacuum degassing has also been tested a beneficial and clean method in producing high quality products. Combination of these two techniques will make degassing more efficient. An experimental device which combines the vacuum degassing and ultrasonic degassing

Ultrasonic Processing of Materials

Ultrasonic degassing,[5–7] an environmentally clean and relatively inexpensive technique, uses high-intensity ultrasonic vibrations to remove hydrogen in molten aluminum. An ultrasonic wave propagating through a liquid metal generates alternate regions of compression and rarefaction.
