Bricks can be cut to customer specified dimensions and orientation. A ground finish is standard. All bricks are cut from HTOT's in house grown HEM sapphire.
All grades are available from Optical Grade 1 to Mechanical grade.
Slicing services are available to provide substrates ready for your finishing process.
Advanced HEM Sapphire Growth
HTOT has two crystal growth facilities located in China. HTOT utilizes Heat Exchange Methos (HEM) Sapphire growth technology because of the many advantages it offers, including:
The most automated crystal growth technology available today.
Accurate and repeatable control of the crystal growth through controlled heat exchange
Crystal growth occurs in a low thermal gradient environment
This growth technology routinely produces the largest sapphire boules in the world with:
The highest quality crystalline structure
The lowest stress
Superior strength and material consistency
Today, HEM technology enables HTOT to produce sapphire boules up to 230Kg. But with HTOT's commitment to research and development, the technology will allow HTOT to reach even larger boules in the near future. HTOT's larger boules mean that sapphire can be used for advanced applications that were not possible just 2 years ago. HTOT has created parts with diameters up to 520mm while maintaining the high quality crystal structure, high strength and low stress of HTOT's sapphire!
