Sapphire, which is a crystalline form of aluminum oxide (Al₂O₃), is an electrical insulator and does not conduct electricity under normal conditions. Its high resistance to electrical conductivity makes it suitable for various applications, including in electronics and optoelectronics, where insulation is required. However, under certain conditions, such as high temperatures or when doped with specific impurities, sapphire can exhibit some electrical conductivity.
