Lab Cultured Synthetic Sapphire Crystal Boule In Orange Color

 

Introduction of Synthetic  Sapphire Crystal Boule

 

Sapphire, which is derived from the Latin Spphins, which means blue; it belongs to the corundum group of minerals in the trigonal crystal system. In the gem world, all colors of gem-grade corundum other than rubies are called sapphires.

 

The main component of sapphire is alumina (Al2O3). Corundum contains trace elements such as iron (Fe) and titanium (Ti), and presents colors such as blue, sky blue, and light blue, among which the bright sky blue is the best.

 

Sapphire has a melting point of 2040°C, and its high melting point makes it inevitable that volatiles such as thermal systems and crucibles exist in the crystal growth environment. A common type of defects in the growth of sapphire crystals by the melt method is that scattering points, bubbles, and inclusions are easily generated during the crystal growth process.

 

It has a relatively large impact on the quality of the crystal. Common inclusions in crystals include impurity elements from raw materials and crucible materials, and fragments of tungsten, molybdenum and other materials used as crucibles, heating bodies and heat preservation devices.

 

One of the reasons for inclusions is that there is a phenomenon of impurity removal in the process of growing crystals. The impurities in the raw materials are discharged to the edge, and the impurities in the crucible diffuse from the edge to the center. When the impurity concentration reaches or exceeds the saturation concentration of the impurity in the melt It precipitates out from time to time, forming a radiation-type impurity group with fewer central inclusions and more peripheral inclusions. The small size of the package is mainly related to the purity of the alumina raw material, the purity of the crucible material, and the density of the crucible.

Basic Structure of Sapphire Boule

 

The composition of sapphire is alumina (Al2O3), which is formed by covalent bonding of three oxygen atoms and two aluminum atoms. Sapphire Boule crystal structure is a hexagonal lattice structure. In terms of color, pure alumina crystals are It is transparent and colorless. The sapphire shows different colors due to the ion penetration of different color elements and the growing sapphire. When titanium ions (Ti3+) and iron ions (Fe3+) are contained in sapphire crystals in nature, the crystals will appear and become blue sapphire (Blue Sapphire). When the crystal contains chromium ions (Cr3+), the crystal will appear red and become ruby (Ruby). When the crystal contains nickel ions (Ni3+), the crystal will appear yellow and become yellow sapphire. Sapphire crystal belongs to the intermediate crystal family and the trigonal crystal system in the symmetry classification of crystals.

 

Application of Sapphire Crystal

 

Sapphire has the best overall performance and has become the most widely used oxide substrate material, mainly used as a semiconductor thin film substrate material, large-scale integrated circuit substrate, etc.

 

Sapphire crystals are also excellent window materials for infrared military devices, missiles, submarines, satellite space technology, detection and high-power lasers (lasers), high-quality optical materials, wear-resistant bearing materials, etc., especially in missile fairings, Submarine windows and atomic clocks play an irreplaceable role in military products.

 

In other civilian applications, sapphire can also be used as transparent electronic materials, lamps and windows, semiconductor wafer carrying devices, thermal insulators, thermocouples, ultraviolet and infrared optical windows, and gravity wave detection instruments.
