About Zircon. Zircon, also referred to as zirconium silicate (ZrSiO 4), is a co-product from the harvesting and processing of ancient heavy mineral sand deposits.Found mainly in Australia and South Africa, zircon 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 …

Technologically Enhanced Natural Radioactive Material (TENORM) contamination is a serious health problem. In applying safe zirconium oxide (ZrO2) in the industrial sector, it is necessary to have environmentally friendly ZrO2, namely very low radioactivity (< 1 Bq/g) and TENORM free. This study aims to obtain a ZrO2 with very …
