Product description
Sapphire wafers have several sell points that make them attractive
to buyers.
- Optical transparency: Sapphire is highly transparent in the visible
and near-infrared regions of the spectrum, making it useful for
optoelectronic applications such as LEDs, laser diodes, and
photovoltaic cells.
- Chemical resistance: Sapphire is highly resistant to chemical
attack from acids, alkalis, and other harsh chemicals. This makes
it ideal for use in chemical processing and other applications
where corrosion is a concern.
- High mechanical strength: Sapphire wafers have high mechanical
strength, allowing them to withstand high stress and pressure. This
makes them useful for use in high-pressure applications such as oil
and gas exploration
Overall, sapphire wafers have a unique combination of properties
that make them attractive for a wide range of applications,
including electronics, optics, aerospace, defense, and more.
