The examples of extraction of metals, iodine, bromine, sodium chloride, potash, boron, arsenic from the liquid phase of heat carriers and, besides, extraction of CO 2 and H
As quartz crystals or rocks made from quartz break down, they form silica sand. Quartz crystals and silica sand have very high melting points, and safety precautions must be taken when melting the mineral at home. When exposed to extreme heat, the quartz or silica sand creates molten glass, which can then be reshaped before it rehardens.

If the sand is not fluidized after the cycle, the resonant heat in the elements will build up in the sand immediately around the elements. This not only causes inconsistent sand temperature, but also shortens element life. By shutting off the sand going into the unit, sand exiting the unit will also stop (a principle of the fluidized bed).
