This chapter describes some of the chemical processes that have been developed to extract beryllium from different types of ore. It covers the Kjellgren-Sawyer sulfate method, the Degussa method, Copaux-Kawecki fluoride extraction, solvent extraction, and leaching and settling. It also provides information on electrolytic extraction and the use of electrorefining.

This chapter discusses the synthesis of important beryllium compounds, including beryllium borides, beryllium carbide, beryllium carbonates, beryllium carboxylates, beryllium halides, beryllium hydride, beryllium hydroxide, beryllium nitrate, beryllium nitride, beryllium oxalate, beryllium oxide, beryllium oxide carboxylates, beryllium perchlorate, beryllium phosphates, beryllium sulfate, and beryllium sulfide.

This chapter addresses in-service monitoring and corrosion testing of weldments. Three categories of corrosion monitoring are discussed: direct testing of coupons, electrochemical techniques, and nondestructive testing techniques. The majority of the test methods for evaluating corrosion of weldments are used to assess intergranular corrosion of stainless steels and high-nickel alloys. Other applicable tests evaluate pitting and crevice corrosion, stress-corrosion cracking, and microbiologically influenced corrosion. Each of these test methods is reviewed in this chapter.

This appendix contains recipes of the electrolytic solutions in which various metals are polished in preparation for metallographic examination.
