Sapphire Tube customizable KY grown plasma containment NMR spectroscopy

Product Description:
 

Our sapphire tubes are manufactured from high-purity single crystal aluminum oxide (99.995%), offering exceptional mechanical strength, thermal stability, and optical performance. With a Mohs hardness of 9, which provides outstanding resistance to scratching, abrasion, and chemical corrosion, making them ideal for demanding industrial and scientific applications.

One of the key advantages of sapphire tubes is their excellent thermal resistance. They can operate continuously at temperatures exceeding 2000 °C and maintain structural integrity even in harsh thermal cycling conditions. In addition, sapphire exhibits superior chemical inertness, resisting attack from most acids, alkalis, and corrosive gases. Optically, sapphire offers a wide transmission range from ultraviolet to infrared, making these tubes suitable for optical and photonic applications such as high-temperature observation windows, laser systems, and spectroscopy equipment.

The KY method grows a large, submerged crystal boule by slowly cooling the melt, resulting in extremely low thermal stress and superior optical homogeneity. This makes it ideal for high-precision lenses. Comapred to EFG method which is faster and reduces machining costs for industrial substrates, the die contact and high thermal gradients often introduce more lattice defects than the KY method.
