How Hard Is Sapphire Glass?
- Introduction of sapphire glass
Sapphire glass is a transparent, extremely hard material that is widely used in high-end watches, mobile phone screens, photographic lenses and other areas. The main component of sapphire glass is aluminium oxide, which has excellent abrasion resistance, high temperature resistance, corrosion resistance and excellent optical properties.
- Hardness of sapphire glass
Sapphire glass has a hardness level of 9, second only to diamond. This means that sapphire glass is quite difficult to scratch and abrade, and marks that scratches or fingerprints will not easily appear on its surface, even during prolonged friction.
- The advantages of sapphire glass
Due to its high hardness, sapphire glass is an effective protective material for mobile phone screens, watch surfaces and other vulnerable parts, while also extending the service life of these components. Furthermore, sapphire glass offers a number of additional benefits, including transparency, high temperature resistance and corrosion resistance, which provide a broad prospect for its application in jewellery, laser devices and other fields.
- The disadvantages of sapphire glass
Despite its high hardness, sapphire glass is also highly brittle, making it susceptible to cracking when it is subjected to impact or violent vibration. In addition, sapphire glass also has a higher manufacturing cost, so the price is higher.
In summary, sapphire glass is an excellent transparent and hard material. Its high hardness, abrasion resistance, and exceptional optical properties offer a vast range of potential applications across numerous fields.
