Norton makes catalyst supports having controlhd structure. T h u s t h e r^for rings and pellets can range from medium porosity to high porosity — for spheres from medium porosity with rough exterior for coating with a catalyst, to high porosity with a network o f open pores uiroughout and rough exterior designed for impregnating with catalyst. Spheres are made in diameters ΎΑ" to \". Rings supplied from 3/32" I . D . , 3 / 1 6 " long, 7 / 3 2 " O . D . to i/ 2 " I.D., 1" long, 1" O . D . Pellets from Vs" χ Ys" to Î4" χ Vi"* Catalyst supports are just an e x ample o f rjr engineering.

Norton FUSED STABILIZED ZIRCONIA has stood u p under 4 7 0 0 ° F in gas synthesis. Its low thermal conductivity and i t s high elec trical conductivity at elevated temperatures make it useful for many special chemical proc esses. N o other refractory is s o chemically stable under high temperature. Norton ALUNDUM porous mediums with "controlled permeability" are ideal for filtra tion, diffusion or aeration. Norton ALUNDUM, CRYSTOLON and MAGNCRITE mixtures for reaction furnaces are supplied in a variety of shapes engineered to your exact requirements.
