Serpek method

The Serpek process is a historic process for the production of ammonia through the hydrolysis of metal nitrides . A plant based on the Serpek process, which was based on the conversion of aluminum oxide to aluminum nitride using coal and nitrogen , was put into operation in 1909 in Niedermorschweiler by the International Nitride Society in Alsace . However, the process did not gain industrial importance.

The formation of ammonia from aluminum nitride takes place according to the equation:

${\displaystyle \mathrm {AlN+NaOH+3\ H_{2}O\longrightarrow NH_{3}+Na[Al(OH)_{4}]} }$.

Ammonia is formed from magnesium nitride as follows:

${\displaystyle \mathrm {Mg_{3}N_{2}+6\ H_{2}O\longrightarrow 3\ Mg(OH)_{2}+2\ NH_{3}} }$
