Abstract

In addition to the high pressure and temperature, process equipment for ammonothermal syntheses has to withstand ammonothermal reaction media: an aggressive mixture of supercritical ammonia with basic or acidic additives. Severe corrosive attack of process equipment can occur under ammonothermal conditions but needs to be minimized for two reasons. Firstly, corrosive attack can lead to safety issues that must not be neglected. Secondly, corrosion products represent a major source of impurities, which represents a critical issue especially for the synthesis of semiconductors. Consequently, measures for minimizing corrosion are of utmost importance for the adequate design of ammonothermal equipment. In this chapter, materials suitable for ammonothermal applications, for pressure bearing parts as well as for internal setups and corrosion protection, and recent investigations on their corrosion behavior will be reviewed with suggestions for suitable applications and protection systems.
