Electronic Grade Alumina
38 AlundumSaint-Gobain Abrasive Grains' electronic grade 38 Alundum® is a very pure aluminum oxide for use in various coating and filler applications. The low levels of soda and iron oxide make these powders useful for electrical insulation and high thermal conductivity applications like cathode heater coil coatings. The tight size control ensures that the material will give a dense and even coating that resists cracking and distortion.
Electronic grade 38 Alundum makes an excellent inert filler and is very effective in ceramic body formulations, offering exceptional abrasion resistance and low shrinkage.
