Product Description General Introduction: The VAD-process synthetic fused silica CFS-100 as a result of significant improvements made to the conventional VAD(Vapor-phase axial deposition) method of optica fiber manufacturing technology.Quartz is extremely high in purity and much lower in OH content than the traditional direct method, thus making it the first synthetic fused silica usable in the semiconductor and liquid crystal display industries.It is the state-of-art technology in optical characteristics because it provides a high ultraviolet transmission, no micro inclusion and a solarization resistance, in addition to heat resistance, mechanical strength, and chemical resistance.Products Name: Fused Silica GlassAlias: fused silica, VAD fused silica, synthetic fused silica, optical glass, etcChemical Resistance:SolutionTreatment Temperature(oC)Treatment Time(H)Test ResultsH2095450.0001-0.00021/100 NHNO3115200.005-0.015% NaOH100101.35Optical Qualities:Item GradeBubbles0-0.03mm2/100cm3StriaeGrade A in one direction(As per Mil-G-174)Birefrengence(Strain)10nm/cm and underFluorescenceNot permitted(Excited wavelength 254nm)Physical Properties:ItemUnitValueDensityg/cm32.201Yong's ModuleKg/mm27280Poisson's ratio 0.17Compression strengthKg/mm2115Bending strengthKg/mm27.0Tensile strengthKg/mm25.6Torsional rigidityKg/mm23150Vickers hardnessKg/mm2900-1030Knoop hardnessKg/mm2650-710Coefficient of thermal expansioncm/cmoC5.5*10-7Softening pointoC1700Annealing pointoC1160Strain pointoC1060Specific heat(26oC)Cal/g.oC0.176Thermal conductivity ratio(26oC)cal/cm.sec.oC2.65*10-3Thermal conductivity ratio(100oC)Cal/cm.sec.oC3.27*10-3Main Applying Fields: Applying Fields:This product can be used in a wide variety of industrial applications for semiconductors, optical and all physical or chemical related research featuring these applications:1).Wafers for various types of devices such as TFT(poly-Si thin-film transistor LCD.),SOI(Silicon on Insulator) etc.2).Photomask substrates for ultra-LSI and LCD. 3).
