Advanced Ceramics of Refractory Cordierite Batts 340*340*15mm
1. Introduction
Cordierite
kiln furniture is manufactured using superior quality body formulations, well regulated production and quality control procedures, and an exceptionally long and tightly controlled firing cycle. These procedures result in a finished product composed of 50% Cordierite and 35% Mullite, with lesser amounts of corundum and other combined mineralogical forms. Glassy phase and uncombined minerals are found in very minor or trace amounts. This combination of high Cordierite and high Mullite yields excellent mechanical properties and remarkably high resistance to thermal shock and warping. Foundry Service’s Cordierite is compatible with all makes and models of hobby and Industrial kilns. We offer over 200 stock sizes in thicknesses of 1/4" to 1-1/2" and in square, rectangular, round, half round, hexagon, and octagon shapes. Our 5/8" thick shelves are recommended up to cone 5, while our 1" thick shelves are used in the cone 5 to 10 range, often substituting for more costly silicon carbide or high alumina shelves at these temperatures. Other Cordierite shapes are also available including posts, racks, tubes, and custom molded parts.
