type: Brick temp limit: 2500F i + k jsciv \f i.: J-M SIL-O-CEL INSULATING BRICK DESCRIPTION: Made from diatomaceous silica, a material composed of millions of micro scopic cells that offer maximum resistance to heat .flow, Sil-O-Cel Insulating Brick are particularly useful where high load-bearing characteristics are required. Sil-O-Cel Insulating Brick are furnished in three types for use as back-up insulation behind refractory fire brick linings or behind insulating fire brick linings. The new Sil-O-Cel 16L brick may also be used for exposed as well as back-up service. AVAILABLE TYPES: Sil-O-Cel Insulating Brick are furnished in three different types as follows: Sil-O-Cel Super--for temperatures to 2500F back up only. Sil-O-Cel C-22--for temperatures to 2000F back up only. Sil-O-Cel 16L--for temperatures to 1600F back up or exposed. USES: Sil-O-Cel Insulating Brick are recom mended for use as back-up insulation in furnaces, kilns, hot blast stoves, soaking pits, boiler walls, oil heaters, regenerators, and similar high temperature equipment in the steel, chemical, ceramic, power, petroleum and glass industries. ADVANTAGES Good Insulating Value Used as back-up insulation, Sil-O-Cel Insulating Brick make it possible to reduce the necessary thickness of the exposed refractory as much as one-third. This re sults in substantial savings in furnace wall construction for all the types of high temperature equipment for which these brick are recommended. High Load Bearing Strength Sil-O-Cel Insulating Brick are made from diatomaceous silica, a natural fossilized material which imparts to the finished brick great strength. The Sil-O-Cel C-22 brick, for example, has a cold crushing strength of 700 lbs per square inch. SIL-O-CEL INSULATING BRICK Specification Data Super C-22 10L Temperature Lhait 2500F** 2000F" 1000F*** Approximate Density 40pcf 30 pet 34pcf Transverse Strength BOpsi 115 psi 00 psi Cold Crashing Strength 300 psi 700 psr 350 psi Linear Shrinkage 231% at 2500F 04% at 2000F 0.7% at 1S00F Reversible Thermal Expansion U%at 2000F 0.7% at less than 0.1% 2000F at 1600F The finm com In this table art everife muss obtained In accord- me* with acceptpd tit methods. **BKh-up paly.
