Ceramic-coated molybdenum sheets / plates

Instead of the traditional thick and poor thermal efficiency ceramics, we manufactured molybdenum sheets / plates with prevention function from welding and reaction, and ceramic coating with a thickness of about 1/5 or less. It allows to operate furnaces more efficiently.
