What Happens When You Smelt Sand?
Microwave heating requires the presence of dipoles in the material to be heated. Sand consists mainly of quartz which does not contain dipoles. So microwaves are not suitable for melting sand. You can e.g. use the focused light of a solar furnace to melt sand.

4 FAQs about [China Solar Melting Sand]
Can sand be used for solar panels?
This high-quality sand is scarce: of the 50bn or so tonnes extracted each year, less than 1% can be used to produce regular glass. A tiny fraction of that is pure enough for solar panels. As China’s leaders seek to revive the country’s economy, and to rebalance it away from property, they are throwing cash at manufacturing firms.
How do green belts and solar-based sand control work?
To combat these issues, Lei noted that green belts and solar-based sand control measures were implemented to “lock” the desert’s edges. These measures not only protect the fragile ecology but also safeguard vital infrastructure like railways and roads.
Can sand be used to make ultra-clear glass?
Yet only a certain sort can be used to make the ultra-clear glass required for smartphones and solar panels. It must have a silica concentration of more than 99.9%, against less than 80% for construction material. This high-quality sand is scarce: of the 50bn or so tonnes extracted each year, less than 1% can be used to produce regular glass.
Why is fine sand so expensive?
Prices are buoyed by the fact that most Asian countries control exports so as to prevent environmental degradation. In America, where fine sand is mostly found in freshwater rivers, tough regulation makes extraction hard. Some manufacturers are now looking for alternatives.
