What is Zircon Sand? What is Zircon Sand used for
About Zircon. Zircon, also referred to as zirconium silie (ZrSiO 4), is a coproduct from the mining and processing of ancient heavy mineral sand deposits.Mined mainly in Australia, it can be used either in its coarse sand form or milled to a fine powder. Its properties ensure that it is used in many everyday products, including ceramic tiles and medical implants, as well as having major

Thorium As Nuclear Fuel: the good and the bad
Thorium fuel is a bit harder to prepare. Thorium dioxide melts at 550 degrees higher temperatures than traditional Uranium dioxide, so very high temperatures are required to produce highquality solid fuel. Additionally, Th is quite inert, making it difficult to chemically process. This is irrelevant for fluidfueled reactors discussed below.
