Zircon Refractory Flour & Sand
Remet Zircon Sand and Flour are milled from raw materials from a newly opened resource with a long manufacturing life. The zircon is dried, milled, screened and subject to magnetic separation. Products have excellent chemical and physical consistency zircon is available in both fully calcined and part calcined forms.
The thermal response of zircon is its major attraction to the investment caster. Not only does it have a low thermal expansion coefficient, but it also has a very predictable and linear response making dimensional prediction of finished parts much simpler and more reproducible.
Other characteristics of zircon in general to be added;
- Very low reactivity (good for prime coats)
- High solids loading capability
- High strength
- Fine particle size for good surface quality
- Excellent rheology
These products are broadly used by foundries producing aerospace castings-equiax, directional solidification and single crystal; and by commercial and art foundries which require premium surface quality.
Remet Milled Zircon
Remet Milled Zircon is dry milled to a controlled particle size distribution from fully calcined zircon sand. It is available in fine (FG), coarse (CG) and extra-coarse (ECG) sizings, which correspond to -400 mesh, -325 mesh and -200 mesh, respectively.
This material is for use in investment casting slurries. It makes up the fine constituent of zircon mold cores and mold facings or a base for zircon foundry washes.
Remet Zircon Sand
Remet Zircon Sand is ideally suited for use as a primary stucco for investment casting molds. It is also used as a constituent of zircon founder cores, mold washes, or as a mold facing material and shell mold component.
