Abstract

Anhydrous Cr Cl(3) has a platelike structure not unlike graphite. However, its volatility is low at elevated temperatures, it is not subject to oxidation and it is not water soluble. The material can be made by reacting Cr(2) (SO(4))3 x H(2)O with C Cl(4).

High Temperature Lubricant

Anhydrous Cr Cl(3) has a platelike structure not unlike graphite. However, its volatility is low at elevated temperatures, it is not subject to oxidation and it is not water soluble. The material can be made by reacting Cr(2) (SO(4))3 x H(2)O with C Cl(4).

The following variations of the use of this material as a lubricant are: 1. In situ generation on metal parts containing chromium as part of the alloy. 2. Incorporation into molded or sintered parts to improve the frictional characteristics. 3. Vapor deposition on hard-to-reach surfaces. 4. Direct application to surfaces as a dry powder or as a suspension in a vaporizing liquid such as trichlorethylene.
