Known for its distinctive pleochroism and historical discovery, this mineral forms under extreme conditions and brings stability to environments where most materials would fail. Furthermore, it is used in the castable refractories industry, where it is mixed with other aggregates to create molds and kiln furniture that can handle the intense heat of molten metal.
This allows exhaust gases to interact with the catalyst efficiently, converting harmful pollutants into less harmful substances before they exit the tailpipe.
