SINGLE CRYSTAL SAPPHIRE
●SINGLE CRYSTAL SAPPHIRE
■Single Crystal Sapphire is playing an ever-increasingly important role as a material for, high reliablility Electronics today due to its excellent mechanical characteristics, chemical stability and light transmission.
■Kyocera mass-produces Single Crystal Sapphire in a vertically integrated manner. From "pulling up" the raw material with EFG (Edge-Defined Film-Fed Growth) methods to machining, Kyocera produces and supplies various products with large diameters or specific shape requirements.
■FEATURES OF EFG METHOD
▲Large Size Material
◆Sizing-up of materials allows for a broader range of applications and uses.
▲Production of Single Crystal Sapphire in Any Desired Sectional Shape
◆Since any desired sectional shape can be obtained in the form of ribbons, tubes, rods,and others, cutting processes can be eliminated, allowing for a reduction in cost.
▲Control of Crystal Orientation
◆Any axis and plane can be produced by instituting proper control during crystal growth.
■FEATURES OF SINGLE CRYSTAL SAPPHIRE
▲High Strength, High Rigidity, High Anti-Abrasion, High Anti-Heat, High Anti-Corrosion Characteristics, and High Anti-Plasma Characteristics.
◆Because of these characteristics, Single Crystal Sapphire is widely used for precision mechanical parts.
▲Stable Dielectric Constant, Very Low Dielectric Loss, Good Electrical Insulation
◆Single Crystal Sapphire is used as a material for substrates in super high frequency regions. It is also used as an insulation material and microwave window. Single Crystal Sapphire has become indispensable in the Electronics Industries.
▲Excellent Light Transmission
◆Single Crystal Sapphire is used for various kinds of vacuum equipment, windows in reaction furnace, scanner windows and caps for optical communication due to its excellent mechanical characteristics and heat resistance.
▲Good Thermal Conductivity and High Heat Resistance
◆Excellent thermal conductivity at low temperatures allows Single Crystal Sapphire as a transparent material to be used in many diverse fields requiring thermal conduction and heat radiation.
