Black Silkprinting TV Shaped Sapphire Glass Crystals for Smartphone
Production description:
Mineral or Sapphire? Hard to decide? 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[56]), and extraordinarily scratch-resistant
Synthetic Sapphire: A synthetic sapphire crystal or “glass” is actually not glass at all. It is a very hard, transparent material made of crystallizing pure aluminum oxide at very high temperatures. Synthetic sapphire has the same hardness as natural sapphire gemstones, but without the colouring agents that give the gems their various hues.
When it is heated, the synthetic sapphire forms round masses, that are then sliced into pieces with diamond-coated saws. These disks are then ground and polished into watch crystals. (One reason sapphire crystals are relatively expensive is that the tools required to cut and polish this extremely hard material are very costly.) Sapphire (whether natural or synthetic) is one of the hardest substances on earth. It measures 9 on the Mohs scale, which is a system for rating the relative hardness of various materials.
