It can be used in a variety of high-precision windows, a variety of lasers and industries. Application, widely used in mobile phone panels, digital cameras and other fields.

Technical Specification

Product Features

The hardness of sapphire is very high, and its hardness is second only to diamond in natural materials, but it needs to be thinned and cut during the manufacturing process of LED devices. Its cutting accuracy is calculated at the μm level. This is for sapphire substrate cutting The technological requirements put forward a very high test.
Due to the wide optical penetration band of sapphire, it has good light transmittance from near-ultraviolet light to mid-infrared light. Therefore, it is widely used in optical components, infrared devices, high-intensity laser lens materials and mask materials.
It has the characteristics of high sound velocity, high temperature resistance, corrosion resistance, high hardness, high light transmittance, and high melting point (2045°C). It is a very difficult material to process, so it is often used as a material for optoelectronic components. At present, the quality of ultra-high-brightness white/blue LEDs depends on the material quality of gallium nitride epitaxy (GaN), and the quality of gallium nitride epitaxy is closely related to the surface processing quality of the sapphire substrate used.

Chongqing Silian Optoelectronics Science & Technology Co., Ltd was founded by China Silian Instrument Group Co., Ltd for the development of LED industry. After the acquisition of Honeywell Sapphire business, the company has become China’s first enterprise with the world’s top-quality large-sized sapphire production and R&D capabilities. The company has the world’s leading high-power sapphire substrates technology. Taking the excellent oppotunity, the company has developed LED packaging, LED lighting applications and other industries in succession to project extension in LED industrial chain. Based on the core-technology of sapphire substrates, we have created an area of 1000 mu (approximately 66.7 hectares) to develop LED industrial china from basic materials to high end products and become the most completed and largest semiconductor energy-efficient in dustrial base in Western China.

Maintaining the enterprise spirit of “People oriented, Natural Selection, Inheriting innovation and Pursuit of Excellence” and the customer tenet of “Silian is guided through customers and stands with customers”, we are committed to provide customers with high-quality sapphire chip substrates, optical window materials, LED packaging devices, and high efficiency LED lighting desplay high end products and creating value for customers.
