Yellow 99.99% Al2O3 Sapphire Single Crystal Lab Grown Rough Materials For Jewelries

Description:

The methods commonly used to grow synthetic sapphire rough stone and cut gemstones include the flame method, the Cheshire crystal pulling method, the hydrothermal method and the flux method, and the diffusion treatment of synthetic cut sapphire. Verneuil (flame hair) materials can be grown in a matter of hours, are inexpensive, and are produced in sufficient quantities. (Figure 1). This material usually needs to be annealed for one to two days to release the pressure. It shows very noticeable curved growth streaks and deformations, and it may require careful positioning if the color distribution is uneven. The flame method of sapphire production originated in Europe, but the production enterprises of such stones appeared in Armenia and China. Some of Verneuil's (Flame process) gem-grade crystal growth facilities have been partially or completely converted to high-purity colorless sapphire production to meet the needs of industrial applications. This results in fewer colors of gem-grade synthetic sapphires available.

Features:

Sapphire is a precious gemstone, a mineral corundum, composed of aluminum oxide (α-Al2O3) and trace elements such as iron, titanium, cobalt, lead, chromium, vanadium, magnesium, boron and silicon. The name sapphire comes from the Latin word "sapphirus," which in turn comes from the Greek word "sappheiros," referring to lapis lazuli. Although natural "colored" sapphires are usually blue, yellow, purple, orange, and green also exist. Sapphire has a Mohs hardness of 9 (second only to diamond's 10 and Moissanite's 9.5), making it ideal for non-decorative applications, such as infrared optics and durable Windows. Also used. , watch crystals and movement bearings, and ultra-thin electronic wafers used as insulating substrates for special-purpose solid-state electronic devices such as integrated circuits and GAN-based blue leds. Sapphire is the September birthday stone and 45th anniversary stone. Sixty-five years later, the Sapphire Jubilee is upon us.

Applications:

The use of colorless materials to diffuse into blue synthetic sapphires will become a common trend, and its production will grow rapidly - a trend that may reduce the price of high-quality synthetic sapphires. This is reminiscent of the beryllium spread natural sapphire trend a decade ago, when the market was flooded with slightly pink orange Papalasha sapphires. We can foresee that this material will present a richer color, and at the same time, it will also give rise to a large number of colorless sapphires with higher purity and clarity and commodity prices. In the future, I would like to see full disclosure of all synthetic gemstone growing techniques and treatments, as such information is extremely valuable to consumers.
