Abstract
A regular topological space is called kappa-normal if any two disjoint regular closed subsets can be separated. In this paper we will show that any product of ordinals is kappa-normal. In addition a generalization of a theorem of van Douwen and Vaughan will be proven and used to give an alternate proof that the product of any countable family of ordinals is kappa-normal.
