List of Sputtering Targets for Thermally Reflective Automobile Glass
Thermal reflective coated glass is also known as sunshine control coated glass, which is commonly known as coated glass, refers to the coated glass with the function of reflecting solar energy. Generally, by coating metal or metal oxide film on the surface of glass, a large number of solar radiation and light can be reflected.
Heat reflecting glass
The heat reflecting glass has good performance of shading and heat insulation. In recent years, the heat reflective coated glass has been widely used in hotels, restaurants and commercial places. With the increasingly prominent problem of energy saving, the heat reflective glass has also been used in civil residential buildings.
Heat reflecting automobile glass
The heat reflection coated glass can effectively reflect the infrared light of the sun (20-25%), block the heat from entering the vehicle (heat insulation performance > 30%), reduce the air conditioning load, maintain good light transmittance (70-75%), and maintain a clear vision. Therefore, the demand of sputtering target materials for thermal reflective coated glass is becoming increasingly strong.
List of sputtering targets for thermally reflective coated glass
So, what are the sputtering targets
that can be used for thermal reflective coating? At present, the commonly used sputtering targets for automobile glass coating are Cr, Fe, Sn, Si, Zn, Mn, Ti, Al, Ag, Ni, Ni / Cr, Cu, Ni / Cu and other sputtering targets of different specifications, as follows:
Chromium sputtering target
Chromium sputtering targets are widely used in hardware tool coating, decorative coating and Flat display coating. Hardware coating is used in various mechanical and metallurgical applications such as robot tools, turning tools, molds (casting, stamping, ...).The thickness of the film is generally 2~10um, and the film requires high hardness, low wear, impact resistance, and resistance with thermal shock and high adhesion porperty. Now, chromium sputtering targets are common applicated in the glass coating industry. The most important application is the preparation of automotive rearview mirrors. With the increasing requirements of automotive rearview mirrors, many companies have switched from the original aluminizing process to the vacuum sputtering chromium process.
Tin sputtering target
Tin is a soft, malleable, ductile and highly crystalline silvery-white metal. When a bar of tin is bent, a crackling sound known as the "tin cry" can be heard from the twinning of the crystals. Tin melts at the low temperature of about 232 ℃(450 ℉), the lowest in group 14. The melting point is further lowered to 177.3 ℃(351.1 ℉) for 11 nm par.
Silicon sputtering target
Silicon sputtering target mainly used in in reactive magnetron sputtering to deposit dielectric layers such as SiO2 and SiN. As an important functional film material, they have good hardness, optical, dielectric properties and wear resistance. The corrosion resistance of Si targets have broad application prospects in optical and microelectronics fields, and are currently widely used as functional materials in the world. Currently, it mainly used for LCD transparent conductive glass, architectural LOW-E glass and microelectronics industry. The silicon sputtering targets can be divided into two types: single crystal and polycrystalline. We produce planar silicon sputtering targets through Czochralski crystal growth method.
Zinc sputtering target
Zinc is a bluish-white, lustrous, diamagnetic metal, though most common commercial grades of the metal have a dull finish. It is somewhat less dense than iron and has a hexagonal crystal structure, with a distorted form of hexagonal close packing, in which each atom has six nearest neighbors (at 265.9 pm) in its own plane and six others at a greater distance of 290.6 pm. The metal is hard and brittle at most temperatures but becomes malleable between 100 and 150 ℃. Above 210 ℃, the metal becomes brittle again and can be pulverized by beating. Zinc is a fair conductor of electricity. For a metal, zinc has relatively low melting (419.5 ℃) and boiling points (90).
Manganese sputtering target
Manganese is a chemical element with symbol Mn and atomic number 25. It is not found as a free element in nature; it is often found in minerals in combination with iron. Manganese is a metal with important industrial metal alloy uses, particularly in stainless steels. Manganese is a silvery-gray metal that resembles iron. It is hard and very brittle, difficult to fuse, but easy to oxidize.Manganese metal and its common ions are paramagnetic.Manganese tarnishes slowly in air and oxidizes ("rusts") like iron in water containing dissolved oxygen.
Titanium sputtering target
Titanium sputtering targets are common used in hardware tool coating, decorative coating, semicondutor components and Flat display coating. It is one of the core materials for preparing integrated circuits, and the purity usually require over 99.99%. AEM also can provide Titanium alloy targets such as tungsten titanium (W/Ti 90/10 wt%) sputtering target, which is an improtant material for semiconductor and solar industry. The density of W/Ti sputtering target we can reach over 14.24 g/cm3, and the purity can reach to 99.995%.
Aluminum sputtering target
Aluminum is a silvery-white, metallic material. It can be found in kitchen utensils, cars, street lights, and the popular aluminum foil food packaging. Although it is not a strong material, it is a good conductor of heat and electricity and is able to form an oxide layer that is resistant to corrosion. When evaporated in a vacuum, aluminum layers form a reflective coating found on telescopes, automotive headlamps, mirrors, packages, and toys. Aluminum sputtering target is widely used in the aerospace, automotive lighting, OLED, and optical industries. Some high purity aluminum targets are used in semiconductor chip, flat panel display, solar cell industries.
Silver sputtering target
Silver is a soft, lustrous element that belongs to the transition group of metals on the periodic table. It has a melting point of 962 ℃, a density of 10.5 g/cc, and vapor pressure of 10-4 Torr at 1,105 ℃. Silver has been used since ancient times in countless products. It is ductile, malleable, and the most electrically conductive of all metals. It is considered a precious metal and can be found in jewelry, solders, paints, and mirrors. It is evaporated under vacuum for the production of semiconductors, sensors, fuel cells, and optical coatings.
Nickel sputtering target
Nickel is a silvery-white lustrous metal with a slight golden tinge. It is widely used in production of sponge nicke and decorative coating area etc.Nickel can form a decorative coating on ceramic surfaces or a solder layer in circuit device fabrication when evaporated in vacuum. It is often sputtered to form layers in the production of magnetic storage media, fuel cells, and sensors. AEM can produce Nickel sputtering targets with high purity and fine grain.Under the same conditions, the coating film is more uniform than the similar products, and the coating area is increased by 10% to 20%.
Nickel chromium sputtering target
Copper sputtering target
Copper is a ductile metal with very high thermal conductivity, electrical conductivity, ductility, corrosion resistance. A freshly exposed surface of pure copper has a reddish-orange color. High-purity copper is used as various wires in the electronics industry, bonding wires for electronic packaging, high-quality audio cables and integrated circuits, liquid crystal display sputtering targets, and ion plating. It is also an indispensable valuable material in atomic energy, rockets, missiles, aviation, space navigation, and metallurgical industries.
