Size can be customized round scratch-resistant synthetic sapphire crystal

Description

Synthetic sapphire is made of bauxite (a type of aluminum oxide), which is mixed with oxygen and hydrogen to bring the material to a melting point of 2050°C. It takes about 15 hours to form sticks (crystalline aluminum) like "corundum". Then the stone is fired again at a high temperature of 1800°C to ensure the stability of the material. Then, the corundum-like material is cut with a very thin diamond polishing blade, and the crystal is cut into thin slices with a diameter of no more than 0.02 mm. The machine can be processed, and then the surface is polished to the required standard thickness, and then the high and low surfaces are processed. After polishing, it can be made into an arc or semicircular crystal surface.

Specification

Regional smelting method—Synthesis principle

The crystalline material is first sintered or pressed into a rod shape, and it is rotated and lowered to the heater, the rod material is melted, and the melting zone is in a floating state, thereby obtaining a purified or recrystallized single crystal.
Features: The crystals produced by the regional smelting method have very high clarity, and it is difficult to see obvious identification features. This method is very costly and is mainly used to produce materials for scientific and technological purposes.

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.
