Organic impurities originating from the decomposition of addition
agents, solution dragin, or the leaching of tank linings and racks can
embrittle the copper deposit and affect the deposit's appearance and
mechanical properties. A batch carbon treatment, Table VI, followed by
filtration or continuous carbon filtration will remove most organics
from the bath. |
Chemistry of copper fluoborate baths. Table VII shows
the composition of a typical acid copper fluoborate bath. If the
fluoboric acid concentration is too low (pH above 1.7), the deposit may
be dull, dark, and brittle. Add boric acid to stabilize the bath and to
prevent the decomposition of the fluoborate to fluoride. The anode film
and its care in a fluoborate bath are very similar to the requirements
described for the copper sulfate bath. |
Potential Acute Health Effects : Extremely hazardous
in case of ingestion. Very hazardous in case of skin contact (irritant),
of eye contact (irritant), of inhalation. Hazardous in case of skin
contact (corrosive). Severe over-exposure can result in death.
Inflammation of the eye is characterized by redness, watering, and
itching. inflammation is characterized by itching, scaling, reddening,
or, occasionally, blistering. |
