Chromite Sand is a naturally occurring spinel consisting primarily of the oxides of chrome and iron. It is a by-product of ferro-chrome production and is mainly used in foundry applications and in glass production.
Chromite Emerges as a New-Age Molding Material …
Chromite also provides very good heat transfer, allowing a skin to form easily on the surface of the casting to reduce penetration. “It also provides better grain-to-grain contact,” Patterson said of SpheriChrome, “so, especially with the conductivity of the chromite there is better heat transfer with that round grain, combined with the stone makeup of the chromite.”

Chromite - Wikipedia
Chromite, when alloyed with iron and nickel creates an alloy called nichrome. Nichrome is described as being 80% nickel and 20% chromium. Due to the alloys that make nichrome, nichrome is seen to be heat resistant up to temperatures of 1250 °C (2282 °F). Due to the high heat resistance of nichrome, ...

STUDY TO IMPROVE THE BREAKING STRENGTH OF THE NO-BAKE ...
breaking strength of no-bake chromite sand-furan resin cores. The Hevi chromite sand produced by a single stage washing of chromite sand was found to exhibit lower breaking strength in service. Forty five samples of no-bake chromite sand mixes were prepared with furan resin at room temperature and 39% humidity from chromite sand
Chromite - Buy Foundry Chromite Sand Product on …
Oregon Resources chromite exhibits unique characteristics due to the rounded stone structure, narrow particle size distribution, and the elimination of fines. This combination results in a higher heat transfer rate, improved core and mold strengths, and the potential for lower binder addition, which in turn produces less binder emissions and ...

(1) Powder bulk density: As CERABEADS ® artificial sand is about half as light as zircon and chromite, it can turn out about twice the number of molds per unit weight. It can also be handled very easily, saving labor and transfer power costs. However, attention should be given to the amount of binder addition.
