Customized Synthetic Rose Red Sapphire Stone Gem Anti Corrosion

Customized Synthetic Rose Red Sapphire Stone Gem Anti Corrosion

Introduction

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.

Basic characteristics

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.
