PRODUCTION OF
TWO-SIDED
COPPER MIRROR
COATINGS BY CHEMICAL METHOD
An aim of the
investigation is a reduction of precious metal expense in the process of mirror
coating production by the chemical method. The method and solution have been
developed for producing two-sided mirror copper coatings on the complex form
surfaces and, in particular, for metallizing Dewar
flasks and flat surfaces.
The method concerns
glass production and vacuum industry, it is mainly oriented at producing
everyday-use goods, e.g. thermoses, as well as producing radioelectronic
devices and reflex lamps.
The use of the known
methods of fixing copper coatings on glass surface does not allow making
two-sided copper mirror surfaces stable and resistible to ambient conditions.
The proposed method
enables the fixing of copper coatings on glass or other surface which is
performed by the activation of the surface in a 0.005-0.15 weight % solution of
silver nitrate. After fixing copper coating, the surface is worked up with the
solution of the stabilizer.
The use of low
concentration solutions of silver nitrate and the stabilization of the copper
covered surface with the stabilizer result in the surface of the article the
high quality mirror.
Mirror copper coating is characterized by
even and high light reflecting power both on the side of the metallic coating,
and on the opposite transparent side of the article as well as by good adhesion
to the surface, on which the mirror is fixed. Reflecting characteristics of the
produced copper mirrors in the region of 640-750 nm wave-length are as follows:
- 80-83% on the side of the copper coating of a glass article;
- 82-85% on the transparent side of a glass article.
Application areas: metallization
of Dewar flasks for producing thermoses, in optics for getting semilucent metallic tapes, light filters, in radio
electronics, for producing decorative goods (in particular, Christmas tree
decorations).
Technical data
- excellent
heat-insulating capacity of Dewar flasks is attained at the expense of the
double-sided reflectivity of the copper coating;
-
of
-
application of the proposed method presumably reduces
consumption of silver to a minimum value.

New
materials for lead-free solders
Lead containing solders are among the top chemicals posing a
great threat to human life and environment. When lead accumulates in the body
it can produce various adverse health effects. All the industrial systems and
devices tend to reduce their environmental and health impact. The industry is
greatly interested in the implementation of lead free soldering especially in
electronics. For economic and industrial reasons, the new lead free solders are
tin-based and substitute traditional Pb-Sn solders.
These binary and ternary systems of eutectic and near eutectic concentrations
based on lead (Sn) are chosen for their low melting
points, good mechanical properties and low cost.
In order to improve mechanical, adhesive, thermomechanical and technological characteristics of Sn-based solders (see Table), small Fe and Ni admixtures
are added. These admixtures reveal positive influence on the solid solders
properties (wetting, creeping, strain). The mixtures stabilize the alloy
crystalline structure, which undergoes essential modifications during
solidification under external fields (electrical and magnetic fields,
temperature gradients, cooling rates, vibrations). The mixtures also prevent
fatigue cracks and contact creeps as well as decrease grains.
Application areas:
Microelectronics, domestic appliances, automobile and space industry.
