Introduction of Synthetic Sapphire Boule

 

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.

Synthetic Sapphire Boule Details

 

 

 

Basic Structure of Synthetic 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.

 

 

Basic characteristics of Synthetic

Sapphire Boule

 

Sapphire single crystal is a simple coordination type oxide crystal, which is anisotropic and belongs to the hexagonal crystal system. The lattice parameters a=b=0.4758nm, c=1.299 1 nm, α=β=90°, γ=120 °.

The light transmittance range of sapphire single crystal is 0.14-6.0μm, covering vacuum ultraviolet, visible, near-infrared to mid-infrared band, and has high optical transmittance in the 3-5μm band; it has high hardness (second only to diamond) , Mechanical and thermal properties of high strength, high thermal conductivity, high thermal shock resistance quality factor; stable chemical properties resistant to corrosion such as rain, sand, and salt spray; high surface smoothness, high resistivity and high dielectric properties .

 

 

These excellent optical, mechanical, thermal, chemical and electrical properties determine its important position and role in the military and civilian fields.

 

(1) Chemical stability: Sapphire has a high degree of chemical stability and will not be corroded during most chemical reactions.

 

(2) Mechanical properties: Due to its high hardness and high strength, sapphire single crystal can maintain high strength, wear resistance and high stability in different environments ranging from ultra-low temperature to 1500 ℃ high temperature. At the same time, it is the oxide crystal material with the highest hardness currently known, second only to diamond up to 9 on the Mohs scale.

 

(3) Optical transmittance: The penetration wavelength range of sapphire single crystal material is 0.19nm-5.5nm, coupled with its excellent chemical stability, abrasion resistance, high hardness and high temperature resistance, make the windows made of sapphire and Sensor optical parts are widely used in high vacuum systems, high temperature furnaces and other harsh environments.

 

(4) Thermodynamic properties: The melting point of about 2050°C, coupled with superior chemical, mechanical and optical properties, make sapphire crystals widely used in many harsh processing environments.

 

(5) Wear resistance: Because of its high hardness and transparency, sapphire crystals are often used to make wear-resistant windows or other precision mechanical parts.

 

(6) Dielectric properties: dielectric insulation and constant dielectric constant.

 

(7) Sapphire also has high tensile strength, erosion resistance, thermal conductivity, and remarkable thermal shock resistance.
