(2) In contrast, molten nonmetallic glass-forming materials, when cooled, do not assume a crystalline structure, but instead retain a structure somewhat like that of the liquid—an amorphous structure. (3) At room temperature, the natural long-term tendency for both types of materials is to a...
A molten metal treatment consisting of a liquid mixture in which fluorinated ketone is dissolved in liquid carbon dioxide at 0.01 to 10 wt % is put in a container, and the molten metal treatment is vaporized, and is fed as a cover gas to be contacted with the surface of a molten metal...

The WArP experiment: a double-phase argon detector for dark matter searches The liquid argon evaporates on or near the surface of the molten metal, expands 840 times in volume and displaces the air, thus purging the furnace atmosphere. Quality castings improves melt quality with SPAL argon shiel...

For injecting gas into a liquid, more particularly a molten metal, a nozzle body (24) is installed in the wall of a liquid-containment vessel, the body (24) having a nozzle passage (25) therethrough. Liquid and gas tightly fitted in a downstream end of the passage is a solid, gas po...

The heat melts the solder paste into a liquid. When the solder cools, it solidifies, leaving a permanent bond between the memory chips and the PCB. The surface tension of the molten solder prevents the chips from misaligning during this process. After the chips are attached, the array is...
Earth’s molten core may be leaking iron, according to researchers who analyzed how iron behaves inside our planet. The boundary between the liquid iron core and the rocky mantle is located some 1,800 miles (2,900 km) below Earth’s surface. At this transition, the temperature drops by mo...
