About Silicon dioxide, ≥99.9%

Vaqora Chemicals supplies Silicon dioxide in Puriss grade, a main-group metal compound registered under CAS number 60676-86-0 with a typical assay of 99.9%. Its molecular formula is O2Si and its molecular weight is 60.08 g/mol. Systematically, it is named dioxosilane. Alternative names: Cristobalite and Quartz.

It is supplied as a white powder. Literature values give a melting point of 1610 °C and a density of 2.6 g/mL at 25 °C. Store sealed in a dry, well-ventilated location away from incompatible materials. Under GHS it is labelled “Warning”, so handle it with suitable PPE and consult the SDS.

It is commonly used for materials research and chemical synthesis. Typical end-use sectors are academic and industrial research.

Standard pack sizes are 100 g, 1 kg and 5 x 1 kg, and every batch ships with a Certificate of Analysis (COA) and we export worldwide.
