Zircon sand pounding material
Zirconia sand is a mineral mainly composed of zirconium silicate, with ZrSiO4 as the main component. It has high melting point, high hardness, and excellent chemical stability, so it can still maintain stable performance in extreme environments such as high temperature and high pressure
- Description
-
Zirconium silicate rammed material is mainly used to improve the slag resistance and thermal shock stability of refractory materials, as well as to enhance their physical properties. Zirconium silicate rammed material is a semi-wet mixture made using phosphoric acid or acidic aluminum phosphate as a binder, with zirconium silicate (or zirconium silicate plus corundum) as aggregate (coarse and fine materials), and an appropriate amount of sintering aid added
