Sapphire is a hard oxide crystal that boasts excellent optical, physical and chemical properties. Its Mohs hardness is as high as 9, second only to diamond, and it has excellent chemical stability, with no absorption peaks in the 0.3-5.5μm spectral range. Consequently, it is suitable for use as a new type of substrate and...

Sapphire is composed of single-crystal aluminium oxide, a compound known for its remarkably strong interatomic binding forces. At room temperature, most chemical substances are incompatible with sapphire. This includes concentrated sulfuric acid, concentrated nitric acid, aqua regia, sodium hydroxide, ammonia water and various organic solvents.

The main cause of cracks in sapphire mobile phone screens is the inherent hardness and fragility of the material, along with the micro-defects introduced during processing. These are compounded by the inevitable impacts, scratches and temperature changes that occur during use. 

Sapphire window plates are key components in harsh working conditions where both electrical isolation and optical access are required simultaneously. This is due to their excellent optical transmittance, electrical insulation performance and mechanical strength. Its high dielectric strength, wide temperature range stability and corrosion resistance have enabled it to be used in a variety...

Sapphire glass, an artificially synthesized single-crystal alumina material, is highly favoured in high-end optics, electronic displays, aerospace exploration and other fields due to its outstanding physical and chemical properties, including hardness second only to diamond, high-temperature resistance and chemical inertness. However, behind these outstanding properties lies an extremely precise and complex preparation process.

The true durability limit of sapphire glass does not lie in its scratch resistance, but in its fracture mechanical properties. It is one of the transparent materials with high wear resistance, scratch resistance and chemical corrosion resistance, but it is not immune to edge impact, concentrated stress, brittle fracture and thermal shock. Its true...

The selection of sapphire glass is fundamentally a matter of balancing performance redundancy and cost, with considerations including heat resistance temperature and light transmittance tolerance. For key components, it is recommended to reserve a 20% performance margin, especially for optical elements such as sapphire glass plates. In scenarios where the customization of intricate shapes...
