| | Zirconium silicide Usage And Synthesis |
| Chemical Properties | Gray solid. Soluble in
hydrogen fluoride; insoluble in water and aqua
regia. | | Uses | Zirconium silicide (Zr3Si2) has been identified as promising material for the neutron reflector in a gas cooled reactor. | | Uses | Zirconium silicate is used for manufacturing refractory materials. It is also used in production of some ceramics, enamels, and ceramic glazes. In enamels and glazes it serves as an opacifier. zirconium silicate is as beads for milling and grinding. | | Uses | Coatings resistant to flame or blast impingement,
special alloys. | | Flammability and Explosibility | Notclassified |
