主要應用：
鑄造業中的鉻鐵礦砂
其特性使該材料可在高強度灰鐵和鋼鑄造廠中用作型 芯和鑄型砂。其高導熱性使其具有良好的冷卻性能，低熱膨脹性使其具有良好的尺寸穩定性。其鹼度接近中性，允許使用多種樹脂黏合系統和無機黏合劑，具有高耐火度和寬篩分分佈。
鋼鐵工業中的鉻鐵礦砂
在鋼鐵生產中，鉻鐵礦砂也被用作填料，用於保護大型鋼包中的滑動水口。
玻璃工業中的鉻鐵礦砂
當磨成細粉時，鉻鐵礦砂可用於生產綠色玻璃飲料容器。

Thanks for the sensible critique. Me & my neighbor were just preparing to do some research on this. We got a grab a book from our area library but I think I learned more from this post. I am very glad to see such fantastic info being shared freely out there.
