  HIGH PURITY CORDIERITE CERAMIC  DISK PLATE STOCK   You are bidding on a High Purity Cordierite Ceramic Disk Plate Stock in mint condition being NOS (New Old Stock). It is made from the high purity mineral Mg2Al4Si5O18 which is also 2MgO·2Al2O3·5SiO2, a magnesium alumino-silicate.   This material is an extremely lightweight material with low thermal expansion and excellent strength, rigidity and thermal shock resistance; and has very good corrosion resistance to chemicals at high temperature, and high use temperature. It may be used for a variety of electrical, mechanical, and thermal applications. Because it has such very low thermal conductivity as most ceramic materials go, it might be used as platen for soldering jewelry or a as setter plate for firing parts in a kiln. The plate may also be used for high temperature dental and jewelry furnaces and as high temperature refractory turntables.  Your imagination is the only limiting factor in the spectrum of possible applications for this component. Be sure to view all photos as they are an integral component of the item description.   The specifications for these components are as follows:   Outside Diameter: Approximately 7.250” (185 mm) Thickness: .500” (12.7 mm)    Please Note: There are visually discernible differences in any or all of the dimensions. These are not precision technical ceramic components. There is no warp or camber Specification for this item. However they are relatively straight and round. There may also be “firing” color variations inherent in the material.   Specific Gravity or Density:   2.6 g/cm3 Water Absorption or Gas Permeability -- Porosity:  10% Fusion Temperature or Melting Temperature:   1450 °C or 2642 °F Maximum Working Temperature:   1300 °C or 2372 °F Thermal Conductivity:  3 W/m* K Expansion Coefficient or CTE from RT-600°C:  3 x 10-6 inches/°C Electrical Resistivity at 20 C:   1014 Ohm*cm Electrical resistance at 600 C:  108 Ohm*cm Modulus of Elasticity:   14 x 106 p.s.i. or 250 GPa.   These components were not specifically manufactured for an individual application; therefore be sure to check the dimensional descriptions carefully for your application. Future returns or requests for refunds, because of some "fit" issue or the like will not be honored. Please check the other Silicon Carbide component variants that are available in my listings for the model or models that best fits your requirement.  Your imagination is the only limiting factor in the spectrum of possible applications for these components and materials.   If you require additional technical information, design, or application engineering consultation, feel free to contact us.
