Sapphires are beautiful gemstones that have been valued for their unique properties and durability throughout history. However, sapphires also have a long history of use in technical applications, dating back to ancient times. In this blog post, we will explore the significance of sapphires in technology and their properties. We will also examine their use in modern-day applications and potential future possibilities for their use in technology.

In Ancient Times

Sapphires were used in ancient times for a variety of purposes. They were highly valued for their beauty and were often used in jewelry, including as beads and pendants. Sapphires were also used in tools, such as knives, and in religious artifacts. They were also ground into a powder and used as a pigment in the artwork.

During the Middle Ages and Renaissance, sapphires became highly prized for their unique properties. They were used in scientific instruments, such as microscopes and telescopes, due to their high refractive index and ability to resist scratching. Sapphires were also used in watches due to their durability and resistance to scratches and cracks.

Modern-Day Applications:

In modern times, sapphires are still highly valued for their unique properties and versatility. They are commonly used in smartphone screens, camera lenses, and scientific equipment due to their high strength and scratch resistance. They are also used in mechanical tools and contraptions due to their durability.

Sapphires are also used in LED lighting due to their high efficiency and long lifespan. They are used in lasers due to their ability to transmit light at high frequencies. In addition, sapphires are used in water purification systems due to their ability to filter out impurities.

Use of Sapphires in Mechanical Applications

Sapphires have been used in various mechanical applications due to their hardness and durability. Here are some examples:

Bearings: Sapphires can be used as bearings in mechanical watches, thanks to their low coefficient of friction and high wear resistance.

Abrasive tools: Sapphires are used as abrasive tools, such as grinding and polishing wheels, due to their hardness.

Pistons: Sapphires are used as piston bearings in high-performance internal combustion engines, as they can withstand high temperatures and pressures.

Endoscopes: Sapphires are used as lens covers in endoscopes, due to their high transparency and scratch resistance.

Semiconductor manufacturing: Sapphires are used as substrates in semiconductor manufacturing, as they can withstand high temperatures and chemical reactions.

Companies that sell and use sapphires in Manufacturing

There are several companies that sell and use sapphires in manufacturing, including:

• Rubicon Technology – a manufacturer of sapphire substrates for LED lighting, semiconductors, and optical applications.

• GT Advanced Technologies – a company that produces sapphire materials for electronic devices, such as smartphones and watches.

• Rayotek Scientific – a manufacturer of sapphire windows, lenses, and other components used in scientific and industrial applications.

• Saint-Gobain Crystals – a supplier of synthetic sapphire used in aerospace, defense, and medical applications.

• Monocrystal – a company that produces sapphire ingots for the semiconductor industry.

• Crystalwise Technology – a manufacturer of sapphire substrates used in the production of LED lights, as well as sapphire wafers used in the semiconductor industry.

These are just a few examples of the many companies that use and sell sapphires for various technical applications.

Future Possibilities for Sapphire Application

There are several potential future applications for sapphires in technology. One area of potential use is in medical implants. Sapphires are biocompatible and could be used to create implants that are both durable and safe for use in the body.

Another area of potential use is in renewable energy devices. Sapphires could be used in solar cells, for example, to increase their efficiency and durability. They could also be used in wind turbines to improve their resistance to wear and tear.

Conclusion

In conclusion, sapphires have a long history of use in technical applications. They are highly valued for their unique properties, including their durability, scratch resistance, and ability to transmit light. Sapphires have been used in a variety of applications throughout history, including in ancient jewelry, scientific instruments during the Middle Ages and Renaissance, and in modern-day technology. The future possibilities for sapphires in technology are vast and exciting, and we can expect to see their use continue to grow in the years to come.
