Functional Ceramics Functional Ceramics is knowledge and technology-intensive products. It has found that the oxide conductor, a solid electrolyte, a piezoelectric, a nonlinear optical material, ferrite, memory materials, solar cells, and other high-temperature oxide superconductor. As electronic products to the compact size, versatility, reliability and high surface density and high integration of development, functional materials also has a continuous development. (1) Electrical Insulation Now commonly Al2O3 is used electrical insulating materials at home and abroad. New electronic insulating materials in recent years, such as AlN ceramics, has excellent properties of high strength, high insulation resistance, low dielectric constant, high thermal conductivity, etc., and the coefficient of thermal expansion can be matched with silicon, the main application as LSI and the power module circuit board heat dissipation. (2) a dielectric material For tuning circuits to protect the majority logic and memory unit ceramic capacitor dielectric material is BaTiO3-based materials, in addition to high dielectric composite perovskite materials to develop a frequency of 105Hz, the dielectric constant of the high dielectric material up to 105 currently it appears grain boundary layer capacitors, dielectric constant conventional ceramic capacitor increased several times or even several times. (3) a piezoelectric ceramic material Common piezo elements: sensors, gas ignition, alarm, audio equipment, medical diagnostic equipment and communications. Typically piezoelectric material is PZT, a new type of piezoelectric ceramic materials are: high sensitivity, high stability piezoelectric ceramics, electrostrictive ceramics, pyroelectric ceramic materials. (4) magnetic ceramic material Magnetic ceramic material can be divided into two types of hard magnetic and soft magnetic material, the former is easy magnetization, but also easy to lose magnetism. Representative hard magnetic material ferrite magnets and rare earth magnets, primarily used for magnets and magnetic storage element. Soft magnetic material easy magnetization and demagnetization, the magnetic field direction can be changed in response to an alternating magnetic field is mainly used for electronic components. (5) superconducting ceramic material From the 1980s to study superconducting ceramics has been a major breakthrough for high-temperature superconducting ceramic materials research and application closely watched. Over the last few years, China's research in this area has been in the world's advanced level. Current application of high temperature superconducting material is moving in high-current applications, electronic applications, anti-magnetic and other aspects of development. (6) anti-bactericidal ceramic material Bactericidal anti-ceramic material is a new generation of functional materials with the development of science and social civilization produced. Inorganic anti-microbial fungicide acc...
Read MoreWhat are stainless steels Iron-base alloys containing sufficient CHROMIUM to form a stable passive film on the surface. 10.5% is the qualifying concentration of Cr for an alloy to be called Stainless Steel. Stainless steels also exhibit remarkable resistance to oxidation at elevated temperatures. Stainless Steel Grades 304L:Basic Austenitic Grad Most economical of austenitic grade. 304LSC: Enhanced Corrosion Resistance This is a tin-modified version of 304L alloy having all the characteristics of 304L, except for improved corrosion resistance while sintered at 1120℃. 410:Martensitic Grade The martensitic form has the lowest corrosion resistance of all P/M stainless steel grades. Low cost. 316L: Austenitic Grade This alloy offers better corrosion resistance and machinability than 304L. With careful processing it can meet the corrosion resistance requirement of the more demanding applications. What makes stainless steels “Stainless” With sufficient chromium(>10.5%), the steel is able to form a protective film on the surface (passivate) in aqueous environments THE FILM: Tin-100-500nm Hydrous oxides (M-xOH), needs Oxygen Dynamic and self-healing Rich in Cr, Mo and Si Damaged by chloride ions, low pH Weak near oxides, precipitates, crystal defects STABILIGY of the film determines corrosion resistance Why Use Stainless Steel Corrosion resistance (Cosmetic & Functional) Oxidation resistance Appearance (luster & color) Elvevated temperature mechanical strength Room temp mechanical strength, toughness Low cost wear resistant material Magnetic behavior with ferritic Our company is a various stainless steel powders manufacturer and supplier.The stainless steel powder is thick and thick to meet different needs.
