Abstract

"The preparation of zirconium powder by several different methods is fully described and evaluated. Most of the methods described are of a rather classical nature and these methods are discussed as taken from their original sources with suggestions for possible streamlining. Flow sheets are provided.

The first series of steps to produce zirconium powder is almost invariably the production of pure zirconium tetrachloride or pure zirconium oxide from the tetrachloride. The processes described include the sodium reduction of zirconium tetrachloride, sodium reduction of the double alkali fluorides, the calcium reduction of zirconium oxide, hydrogen embrittlement and comminution of reduction products.

The hydride method as utilized for zirconium sponge is a good process to make zirconium powder. This method which is described in detail can be nicely used to produce zirconium hydride or zirconium powder from any pure reduction product. While arc-melted or massive zirconium can be hydrided, material with larger surface area, e.g. sponge, is more favorable.

The calcium reduction of zirconium oxide also has potential method to produce a good zirconium powder. It is concluded that suitable zirconium powder will be available as an increased demand arises. Methods tor safe handling of zirconium powder are briefly described"--Abstract, page 2.
