Technology development and production expansion sapphires and sapphire wafers for production of LEDs and compounds for photovoltaics

Monocrystal Company is the leader in the world market of synthetic sapphires used in light emitting diodes, smartphones, tablet PCs and smart watches, for glasses of cameras, sensors of fingerprints as well as displays.

Monocrystal is the largest manufacturer of the world market of sapphires for LEDs. Currently, the Company takes 50% of the world market of sapphires for light emitting diodes. 95% of its products are exported to 25 countries. Each second diode in the world is manufactured using the Monocrystal’s raw materials. Four of 10 world leaders in the field of LED production use sapphire wafers manufactured by Monocrystal. Eight of 10 largest world companies processing sapphire use sapphire ingots manufactured by Monocrystal.

On 2018, Monocrystal started production of crystals of synthetic sapphires of large and extremely large diameters using Kyropoulos procedure by proprietary technology (their weight is from 120 to 400 kg) and sapphire six inch wafers. Transfer to large crystal growing made it possible for the Company to decrease the cost by more than 20%.

Within the frames of the project, Monocrystal produces three types of products in high demand in the global markets.

Sapphire cylinders: single-crystal sapphires in cylindrical form for production of sapphire wafers.

Sapphire wafers: thin plates of sapphire used in opto- and microelectronics to grow layers of various materials (gallium nitride, silicon and so on). Such substrates are the most effective for LED production due to the best quality-to-price ratio.

Aluminum, silver, and aluminum-silver pastes: essential components for metalizing silicon solar elements.
