ZnSiO3

Zinc silicate, with the chemical formula ZnSiO3, is an inorganic compound. It is also known by its mineral name, willemite. Willemite is a naturally occurring mineral, typically found in metamorphic rocks and in some hydrothermal veins. It crystallizes in the trigonal crystal system and is known for its characteristic fluorescence, often emitting a bright green light under ultraviolet radiation.

The compound can be synthesized in laboratories through various chemical methods. One common approach involves the solid-state reaction between zinc oxide (ZnO) and silicon dioxide (SiO2) at elevated temperatures. Another method is through sol-gel processes, which allow for greater control over particle size and morphology.

ZnSiO3 has found practical applications in several fields. Due to its strong luminescence, it has been historically used as a phosphor in cathode ray tubes (CRTs) for television screens and oscilloscopes. It is also utilized in fluorescent paints and security inks. In materials science, zinc silicate is explored for its piezoelectric properties and potential use in sensors and actuators. Its relatively low toxicity compared to some other phosphors makes it an attractive option for certain applications. The compound is generally stable under normal conditions.
