Iron Chromite powder 325# for Green glass lamp tube
46% Cr2O3 Iron chromite powder 325# is produced using fine grinding technology to get fine Ferro Chromite flour. Its raw materials are chrome ore sand imported from South Africa and Zimbabwe. When chrome ore sand is ground to 325 mesh, its chromium oxide purity will decrease by 0.1-0.2%. In our factory, we can ensure 325# chromite powder Cr2O3 content 46% by adding high-grade 48-50% chromite sand.
UV glass tube is a light source pipe made of sodium calcium glass or quartz material that uses ultraviolet light as the light source. Usually used in UV curing equipment, if the glass tube is made green, it can be used as a UV light source device for capturing mosquitoes. Green UV lamps can attract the attention of flying insects more. Iron Chromite powder, as a commonly used green glass pigment, can be added to sodium calcium glass lamps to create light green transparent glass tubes. The type of chromite powder used is 325#, and its particles pass through a 325 mesh sieve.
