High-Strength Silica Matrix Composite Insulator
Booth 3061. Refractory Sheet Type RSLE57 is a low expansion, high strength, reinforced silica matrix composite. This material is for use as a high strength insulator in induction hot press applications w. Low thermal expansion coefficient and high hot strength combine to give the material thermal shock resistance. The low coefficient of expansion 0.3 × 10-6 C provides resistance to thermal shock up to 1200 C in an oxidizing atmosphere and permits its use with rapid variation in temperature in that zone. Beyond 1200 C, it transforms into a crystalline structure while maintaining its properties up to 1650 C, providing there is no significant fall in temperature. At temperatures above this, the material will exhibit surface glazing. Additional features include low thermal conductivity, excellent electrical insulation, high chemical purity, and excellent resistance to corrosion from molten metal and glass.
