How do I remove agbr marks from a quartz boat after CVD?

03 September 2024 1 10K Report

We are dealing with agBr via CVD. After CVD, marks like that remain on the quartz boat where agbr was placed, and I wonder how to remove them.

Jürgen Weippert

AgBr is soluble with a concentrated NH3 agent under formation of the Diamminsilver complex.

Safety advice: under certain conditions, Diamminsilver may be converted to highly explosive silver azide, so please be careful about the disposal.
