Sapphire rod is perfect material for high temperature application with no change to its shape and dimension because of its extreme High Softening Point over 2000°C. 
Sapphire rod is chemically inert and resistant to attack from most processing environments, such as Acid and Alkalis at temperatures up to ~1,000 °C.
Sapphire rod is bio-inert. It is the ideal material for bio-engineering, dental and medical bone implants.
Sapphire rod is suitablel for rod bearing application due to its strong wear and abrasion resistance.
