What is the Mohs hardness of zircon?
2021-11-12
Zircon, as a common mineral, is widely found in the earth's crust. Its unique physical properties, especially its hardness, make it widely used in jewelry, handicrafts and other fields. So, what is the Mohs hardness of zircon?
Mohs hardness, referred to as Mohs hardness, is a measure of mineral hardness standards. It is determined by comparing the scratch ability of different minerals. This hardness test method has its limitations, but it is still a valid evaluation tool for common minerals and gemstones.
The Mohs hardness of zircon is usually between 6 and 7.5. This means that zircon can easily scratch glass (Mohs hardness of about 5.5), but for harder materials such as steel knives, its ability to scratch is relatively weak. This hardness range makes zircon a good choice in jewelry making because it has a certain wear resistance and is easy to process.
It is worth noting that the hardness of zircon is also affected by other factors. For example, the internal structure and chemical composition of zircon can affect its hardness. In addition, the processing of zircon, such as heat treatment, chemical treatment, etc., may also change its hardness.
In the jewelry industry, it is very important to know the hardness of zircon. Suitable hardness means that the gemstone is not easily damaged during processing and can maintain a long luster during wearing. At the same time, the hardness of zircon also determines its stability in different environments. For example, high hardness zircon is more resistant to wear and is suitable for long-term wear.
In general, the Mohs hardness of zircon is usually between 6 and 7.5, which makes it widely used in jewelry making and handicrafts. However, the specific value of hardness may vary depending on the internal structure and chemical composition of the mineral. In practical applications, understanding the hardness of zircon is very important for selecting the right gemstone and extending its service life.
