Triethanolamine Alumina Dispersant
CAS Number: 102-71-6
Triethanolamine (TEA) is an amino alcohol used as a surface modifier and dispersant for alumina powders in non-aqueous ceramic processing systems. Its amine and hydroxyl groups adsorb onto alumina surfaces, reducing inter-particle friction and improving flow in hot-press and injection molding compounds. TEA also acts as a pH buffer in aqueous alumina slips.
