Ceramic-coated molybdenum sheets / plates

Rather than traditional thick ceramics with low thermal efficiency, we produce molybdenum sheets and plates designed for protection against welding and reactions. Combined with ceramic coatings approximately 1/5 the thickness or less, these molybdenum sheets and plates enable more efficient furnace operations.
