WEAREONE University Laboratory Test Crucible Quartz Glass Crucible High Purity Quartz Crucible Heating Quartz Beaker Products Quartz Crucible (with Cover) (300ml)

✨Quartz glass crucible is a kind of special glass containing only silicon dioxide single component, fine work is clearly visible inside, thickened glass inner wall thickness 2mm, high transparency.✨Quartz crucble JGS-2 ultraviolet quartz glass: quartz glass produced with quartz raw materials and chlorine oxygen flame contains a few +PPM of metal impurities · There is an absorption peak at 2730NM (light base content 100-200PPM)· There are streaks and star structure it is a good material in the band range of 220-2500 PMbr>✨Quartz glass crucible has high hardening temperature and can be used for a long time. In particular, the chemical stability at high temperatures is unmatched by any other engineering materials. The resistance value of quartz glass is equivalent to 10,000 times that of ordinary glass, which is an excellent electrical insulation material and has good electrical properties even at room temperature.✨Quartz glass crucible performance parameters:Density: 2.2G/CM3，Compressive strength: 1100MPA，Bending strength: 67 MPA，Tensile length: 48 MPA，Poisson's ratio: 0.14-0.17，Young's modulus: 72000 MPA，Rigid modulus :31000 MPA，Heating working temperature :5.5*10-7CM/CMC，Long-term use temperature :2012 degrees Fahrenheit，Dielectric constant :3.7-3.9，Dielectric loss coefficient :> 1 * 104，Mohs hardness :5.6-6.5，Deformation point :1280°C，Softening point :1780°C，Annealing point :1250°C，Specific heat (20-350°C):670J/KG°C，Refractive index: 1.4W/M°C，Thermal expansion coefficient: 1.4585°C，Short-term use temperature: 2642 degrees Fahrenheit，Resistivity: 7*107Q/CM，Dielectric absorption coefficient: > 4 * 104✨Product use: burning solid substances; Evaporation of solution; Concentration or crystallization (evaporation dish should be selected if available, of course, the crucible can also be used for solution evaporation, concentration or crystallization)✨Note: 1.
