1pc High-Temperature Quartz Crucible 20ml-2000ml, Thick-Walled Lab Crucible for Acid Resistance and Thermal Stability(with Cover 2000ml)

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 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/CM3Compressive strength: 1100MPABending strength: 67 MPATensile length: 48 MPAPoisson's ratio: 0.14-0.17Young's modulus: 72000 MPARigid modulus :31000 MPAHeating working temperature :5.5*10-7CM/CMCLong-term use temperature :2012 degrees FahrenheitDielectric constant :3.7-3.9Dielectric loss coefficient :> 1 * 104Mohs hardness :5.6-6.5Deformation point :1280°CSoftening point :1780°CAnnealing point :1250°CSpecific heat (20-350°C):670J/KG°CRefractive index: 1.4W/M°CThermal expansion coefficient: 1.4585°CShort-term use temperature: 2642 degrees FahrenheitResistivity: 7*107Q/CMDielectric absorption coefficient: > 4 * 104Product 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. It can be directly, and cannot be cooled quickly after heating. Use the crucible pliers to remove 2. When heating, put the crucible on the mud triangle. 3. Stir when evaporating, and use the waste heat to evaporate
