Product Description Product DescriptionGeneral Introduction: This ZERODUR glass-ceramic has been one of the Germany manufactuer's most unique and extraordinary products for over 50 years. With an extremely low-thermal-expansion, it's essential for a large number of demanding high-tech applications requiring exceptional precision.Products Name: Germany Zerodur Zero Expansion Glass Ceramic Alias Germany Zerodur Zero Expansion Glass Ceramic, Zerodur glass, Zerodur fused silica, Zerodur quartz, zerodur, Zerodur K20, K20 glass, K20 glass,etc Our AdvantagesMain Characteristics:1).Highly accurate under extreme conditionsThe extremely low-thermal-expansion of ZERODUR is homogenous throughout the entire bulk volume, which makes it ideal for a large range of applications involving precise positioning or imaging under changing temperature conditions.2).Impressive machinability from small to largeThanks to its extraordinary machining properties, ZERODUR can be manufactured in a variety of sizes and shapes, from tiny prisms to meter-sized mirror blanks. High degree light-weighting and surfaces optimized for bending strength are key areas of the manufactuer's expertise, which makes ZERODUR ideal for space applications.3).Product variantsTHis ZERODUR is suitable for many high-tech applications, ZERODUR TAILORED offers the best material for individual temperature requirements, and ZERODUR K20 is suitable for your high-temperature applications.4).Low-thermal-expansion even in harsh environmentsThe inorganic, non-porous lithium aluminum silicon oxide glass-ceramic, ZERODUR is characterized by its extremely low-thermal-expansion, which is homogeneous throughout the entire volume. Additionally, it possesses a very low rate of imperfections, high strength compared to other glass-ceramics and is transparent to visible light. Smooth surfaces with a roughness in the sub-nm range are also achievable. Product ParametersThermal Expansion Properties:ZERODUR can be supplied with a mean coefficient of linear thermal expansion (CTE) in the temperature range 0°C to 50°C in three expansion classes as follows:CTE (0°C; 50°C) Specification tolerancesExpansion Class 0: 0 ± 0.02 · 10-6/KExpansion Class 10 ± 0.05 · 10-6/KExpansion Class 20 ± 0.10 · 10-6/KTighter tolerance available upon request.Thermal Conductivity:ITEMZerodurZerodur K20Thermal Conductivity (W/(m?K))1.461.63Thermal Diffusion (×10-4m2/s)0.72-Speci?c Heat (kJ/(kg?K))0.800.90Mechanical Properties:ItemUnitZerodurZerodur K20Densityg/cm32.532.53Yong's ModuleGPa90.384.7Poisson's ratio 0.240.25Compression strengthGPa--Bending strengthMPa--Tensile strengthMPa--Torsional rigidityGPa--Vickers hardnessGPa---Knoop Hardness HK 0,1/20 (ISO9385)-620620Abrasion Aa*-56.1-Refractive index nd-1.5424-Softening pointoC--Annealing pointoC--Strain pointoC--Specific heat(26oC)kJ/kgK2.552.55Thermal conductivity ratio(26oC)cal/cm.sec.oC--Thermal conductivity ratio(100oC)Cal/cm.sec.oC--Main Applying Fields: Applying Fields:ZERODUR has become a determining factor in the performance and quality of many spectacular applications that employ modern technology:1).Stages and mirrors for IC and LCD lithography equipment2).Mirror substrates for segmented and large monolithic astronomical telescopes3).Ultra light weight mirror blanks4).Standards for precision measurement technology5).High precision mechanical parts, e.g. ring laser gyroscope bodies***** Matching Custom Manufacturing Serivce:Including Moulding, CNC machining, Polishing, Particle beam processing, Magnetic flux conversion processing, Grinding, Coating, Lightweighting, Custom Shaping, Counterbores, Drilling & Coring, Edge & Bevel Polishing,3D Contouring, Bevels & Chamfers, Steps & Slots, Laser Cutting & Marking, Metrology & Inspection, Precision Pitch Polishing, Double-Sided Polishing, Optical Assembly, Measuring, etc.Matching processing equipments;1).Single side lapping and polishing machines2).Duble sided polishing machines3).Ring throwing machines4).DMG five-axis five-linkage spherical milling machine5).DMG ultrasonic machining center6).Super large scale gantry cnc machining center (2.0*2.0m)7).Super large scale surface grinder (1.6m*1.6m)8).CNC cutting machines9).Thin plate cleaning machines10).Ultrasonic trough cleaning machines11).Plane interferometers12).Two dimensional detectors13).Ion beam polishing machines14).Magnetorheological polishing equipmentsMain Export Countries & Areas: Usa, Uk, Japan, Germany, Spain, France, Swiss, Korea, Russia, Pakistan, India, Portugal, Canada, New Zealand, Australia, Saudi Arab, Turkey, Finland, Poland ,etc.Raytekoptics Extra value added services offered:1).
