Abstract
Beryllia is prepared for direct autocatalytic plating of a metal film by immersing it first in a sodium hydroxide solution for roughening the surface uniformly, rinsing it in water, then immersing it in a fluoride-based solution for etching silica and magnesium from the grain boundaries, rinsing it in water and then plating the beryllia by conventional methods for metallizing non-conductors.
