LARGE 12 + INCH DIAMETER THIN HIGH PURITY ROUND ALUMINA CERAMIC SETTER PLATE DISK You are bidding on ONE (1) only of a Large Diameter Thin High Purity Round Alumina Ceramic Disk or Setter Plate. It is in mint condition being NOS (New Old Stock). They are made from 99.8% purity Aluminum Oxide (Al2O3) which of course is Alumina. Generally the balance of composition for this purity Alumina material is of Silicon Dioxide (SiO2) which is Silica. This material has very high hardness, very high stiffness, very good corrosion resistance to chemicals at high temperature, and very high refractoriness or use temperature. They may be used for a variety of electrical, mechanical, and thermal applications. They may be used as setter plates for firing parts in a kiln. The may be used for high temperature furnaces and as high temperature refractory turntables. They may also be used for jewelry or for applications requiring high wear or abrasion resistance. 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: Diameter: Average approximately 12.3125 or 12 5/16” (313 mm) Thickness: Average approximately 0.187” or 3/16" (0.88 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 flat. There may also be “firing” color variations inherent in the material and evidence of impurity resulting in iron spots . The thermal shock resistance is not very high so exercise rule of thumb caution. “The larger the piece of material the slower the rate of temperature increase should be applied to the piece.” Heat up slowly to avoid cracking in use. Specific Gravity or Density: 3.9 g/cm3 Water Absorption or Porosity: 0% Fusion Temperature or Melting Temperature: 2030 °C or 3686 °F Maximum Working Temperature: 1800 °C or 3272 °F Thermal Conductivity: 25 W/m* K Specific Heat: 0.9 J/g*K Expansion Coefficient or CTE: 7.5 x 10 E-6 inches/°C Electrical Resistivity at 20 C: 10 E¬14 Ohm*cm Electrical resistance at 600 C: 10 E 8 Ohm*cm Modulus of Elasticity: 44 x 10 E 6 p.s.i. or 350 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.
