| 配方组成： |
Sensitizing is followed very closely by one or two thorough rinses
in high-purity water and immediate immersion in the activator solution.
The purpose of the activator is to put a thin catalytic layer of a noble
metal on the surface of the nonmetal. The activators are generally made
up of noble metal chlorides, but other complexes (hydroxide---Pd(OH)6-)
may be used and, where silver is used, the ammoniacal nitrate is
preferred (silver mirroring technique). Platinum, silver, gold, rhodium,
and palladium have all been used, with the latter two being the most
common today. A typical palladium solution is
Hydrochloric acid/10 m/l
Palladium chloride/1 g/l |
