The question of Chromite vs. Zircon has always been a very difficult subject because good quality Zircon has always been a very difficult subject because of good quality Zircon sand performs extremely well, and has been used as a benchmark in the production of quality Zircon sand performs extremely well, and has been used as a benchmark in the production of quality castings over the past 20 years. castings over the past 20 years. However, during the past 6 to 8 years Zircon has become very variable However, during the past 6 to 8 years has become very variable Zircon and the so-called foundry grades are giving some foundries severe problems due to contamination. and the so-called foundry grades Foundries are giving some severe problems due to contamination.
When the cleanliness of Chromite is at turbidity levels of less than 100 ppm Chromite will perform better When the cleanliness of Chromite Chromite is at turbidity levels of less than 100 ppm will perform better than Zircon in the heavy steel foundry environment. Zircon than in the heavy steel foundry environment. This is supported by our customer list, which This is supported by our customer list, which includes the majority of the heavy high quality steel foundries worldwide. includes the Majority of the heavy high quality steel Foundries worldwide.
