About synthetic sapphire crystal

The Kyropoulos process (KY process) for sapphire crystal growth is currently used by many companies in China to produce sapphire for the electronics and optics industries.
High-purity, aluminum oxide is melted in a crucible at over 2100 degrees Celsius. Typically the crucible is made of tungsten or molybdenum. A precisely oriented seed crystal is dipped into the molten alumina. The seed crystal is slowly pulled upwards and may be rotated simultaneously. By precisely controlling the temperature gradients, rate of pulling and rate of temperature decrease, it is possible to produce a large, single-crystal, roughly cylindrical ingot from the melt.
After single crystal sapphire boules are grown, they are core-drilled into cylindrical rods, The rods are sliced up into the desired window thickness and finally polished to the desired surface finish.


Used as a window material

Synthetic sapphire (sometimes referred to as sapphire glass) is commonly used as a window material, because it is both highly transparent to wavelengths of light between 150 nm (UV) and 5500 nm (IR) (the visible spectrum extends about 380 nm to 750 nm, and extraordinarily scratch-resistant. The key benefits of sapphire windows are:
* Very wide optical transmission band from UV to near-infrared
* Significantly stronger than other optical materials or glass windows
* Highly resistant to scratching and abrasion (9 on the Mohs scale of mineral hardness scale, the 3rd hardest natural substance next to moissanite and diamonds)
* Extremely high melting temperature (2030 °C)

About Our Company & Factory

ZMKJ has been fabricating micro to large sapphire windows, sight glasses and flats for over 10 years. Although sapphire is often more costly than glass and other transparent materials, its exceptional properties can ultimately save money and reduce critical down time, often eliminating the need for PM periodic replacements.

We are also specialize in providing a varity of materials wafers, substrates, components, products are widely used in electronics, optics, optoelectronics and many other fields. We've been working closely with many domestic and oversea universities, research institutions and companies, provide customized products and services for their R&D projects.

It's our vision to explore and develope cutting edge application of new materials with customers together.
