Sapphire is an attractive substance, often considered a precious gemstone. It can be produced in comparatively large dimensions due to its inertness and therefore can be machined at high temperatures. It is often used as a material for the epitaxial deposition of Gallium and Silicon Nitride.
In the Machining Sapphire process require materials to be grounded to an appropriate size, tolerance and finely polished so that the material will be useful as planned. This process creates lots of difficulties in manufacturing challenge, it is always recommended to machine sapphire under expert supervision in order to succeed.
Sapphire is a form of the material Alumina (Aluminium Oxide – Al2O3). It is the single crystal form of Machining alumina used in engineering ceramics. Its single crystal structure has no porosity or grain boundaries. Saphire products have a measured density, which is close to the hypothetical value of pure Alumina material.

Industrial Applications of Sapphire:
- It can be used for insulating substrate applications in high-frequency, high-power CMOS integrated circuits.
- The resistance of sapphire to phosphoric or hydrofluoric acid is also significant.
- In endoscopic inspection tools, sapphire is often used as a window material.
- The fine microstructure of sapphire combined with polishing and skilled machining techniques produces cutter edges and ultra fine blade.
- Sapphire has a high degree of impact erosion, therefore it is used as a material for premium transparent watch face.
- Used in devices where corrosion resistance and high temperature is required.
- Stiffness, high hardness and single crystal structure lead to use of sapphire material in many engineering or industrial components.
- Sapphire lenses can be used in imaging applications, laser optics, and sapphire medical optics.
