Strontium metal sputtering target is a high-purity, low-density and chemically active sputtering target, mainly composed of strontium metal, which has important applications in the fields of electronic devices, optical films and superconducting materials.<\/p>\n
Characteristics<\/p>\n
Appearance: Silver-white metallic luster.<\/p>\n
Density: about 2.64 g\/cm\u00b3.<\/p>\n
Melting point: 769\u00b0C, which needs to be reached in order to melt it during preparation and use.<\/p>\n
Thermal conductivity: 35 W\/m\u30fbK, high thermal conductivity, heat transfer is relatively fast, more important in some applications that require rapid heat dissipation or thermal management.<\/p>\n
Coefficient of Thermal Expansion: 22.5 x 10-\u2076\/K, with relatively small dimensional changes when the temperature changes, which helps to ensure the stability of the target material and the uniformity of the film during the sputtering process.<\/p>\n
Strong chemical activity: it is easily oxidized in the air, so it is necessary to take appropriate protective measures during storage and use, such as preservation in a vacuum or inert gas environment, and the use of oil packaging, etc., to prevent it from chemical reaction with the oxygen and moisture in the air.<\/p>\n
Applications<\/p>\n
Electronics: In the manufacture of electronic devices, Strontium is used for the preparation of thin films with special properties, e.g. as a dopant or as part of the electrode material in semiconductor devices. For example, by sputtering Strontium metal targets, a strontium-doped film can be formed on a silicon substrate, which is used to regulate the electrical properties of semiconductors and improve the performance and reliability of devices.<\/p>\n
Optical thin film: It can be used to prepare optical thin film, such as in the field of optical lens, display screen, etc. By adjusting the sputtering process parameters, the thickness and refractive index of the film can be controlled, so as to realize the optical effect of transmittance increase, inverse reduction, etc., and to improve the performance of the optical components.<\/p>\n
Superconducting materials: Strontium metal is an important component of some high-temperature superconducting materials, through sputtering technology Strontium metal targets deposited on a suitable substrate, can form superconducting thin films, for the superconducting device research and development to provide basic materials.<\/p>\n
Other fields: It can also be applied to magnetic recording materials, sensor materials and other fields. For example, adding strontium element in magnetic recording media can improve the performance of magnetic recording materials, increase storage density and read\/write speed; in sensor materials, using certain characteristics of strontium metal, sensor films sensitive to specific substances or physical quantities can be prepared.<\/p>\n","protected":false},"excerpt":{"rendered":"
