Synthetic sapphire is also referred to as Corundum, which has excellent chemical stability and mechanical property. It retains its high strength at extremely high temperatures. Synthetic sapphire has superior dielectric and electrical properties and is widely used across an application that requires reliability, optical transmission, and strength is required such as electrical insulator and thin film depositor. Moreover, it is also used in the medical industry where it is used to produce hip joint endoprostheses. Furthermore, due to its optical properties are becoming an ideal choice of engineering materials that can deal with high pressure, extremely high temperature and harsh chemicals.

The global synthetic sapphire market is estimated to account for slightly less than US$ 5.7 billion in terms of value in the year 2018 and it predicted to grow at a CAGR of 8.3% during the forecast period (2019-2027)


Growing application of optical-grade sapphire windows across industrial instruments such as air and gas analyzers/monitors, Ultra Violet (UV) and Infra-Red (IR) windows and lenses and biometric devices are projected to fuel the global synthetic sapphire market over the forecast timeframe. Moreover, the growing adoption of radio frequency integrated circuits (RFICs) in high-frequency electronic goods such as smartphones that uses silicon on sapphire wafers is further expected to propel the market growth.

Market Opportunities

Rising application of synthetic sapphire across new sectors such as aerospace, military, and defense will provide lucrative growth opportunities to the manufacturers of synthetic sapphire. Military IR windows, missile domes, large sapphire windows, and transparent armors are gaining importance in the aerospace and defense industries. Therefore, the rising application of synthetic sapphire from the aforementioned application is expected to propel the market growth over the forecast timeframe.

Market Restraints

Defects in the manufacturing process as existing technologies fails to produce large-area sapphire crystals with required thickness for the specific application is expected to restrict market growth. Moreover, the produced crystals may have bubbles inside the sapphire boules and low-angle grain boundary, which affects the epitaxial growth during the production of LED. This factor is expected to hamper the market growth of synthetic sapphire.

Key Takeaways:

On the basis of end-user, Light-emitting diode (LED) manufacturing segment has dominated the global synthetic sapphire market in 2018 with a 32.1% of market share in terms of value, followed by consumer electronics and semiconductors.

Market Trends

Increasing focus of manufacturer to introduce innovation in sapphire- based product is a major trend that has been observed in the market and this trend are expected to augment the market growth. For instance, in October 2018, Essilor ANZ has launched the most advanced the progressive lens in the market with a series of roadshows around Australia and New Zealand. Moreover, the company has introduced its new Crizal Sapphire Ultra Violet (UV) coating, “the first anti-reflection coating designed to reduce reflections from all angles on the front and back of the lens caused by natural and artificial light”.

The growing trend of introducing innovative medical devices such as sapphire infusion pumps is expected to foster the market growth of synthetic sapphire. For instance, in November 2019, The Eitan Group launched a new preventative maintenance servicing tool to cut maintenance costs and runtime on its Sapphire infusion pumps. This factor is expected to foster the market growth of synthetic sapphire.
