Our production of bismuth-based chemicals has placed
HEK GmbH at the top of the global market. All of our products meet
the highest quality standards and are available in a wide variety
of specifications and purities.
The field of application of our bismuth-based chemicals is very broad
and extends from the pharmaceuticals industry via the substitution
of toxic lead compounds to the electronics industry, where bismuth
compounds are frequently used because of their unique properties.

Varistors
Bismuth oxide plays a key role in the production of modern
electronic components. It improves the electrical properties
of ceramic materials thus allowing the hitherto impossible to
be achieved

Ceramics
In the production of glass frits and ceramics, there is a growing
tendency towards substituting toxic lead with bismuth. This
development is being accelerated even further by the higher
chemical stability of bismuth as well as its lower melting point.

Vehicle construction
For reasons of environmental compatibility, the automobile
industry is increasingly tending towards drastically reducing
the levels of lead compounds used in vehicles. Here too, bismuth-based
systems offer a sound alternative to lead.

Pharmaceuticals industry
Due its outstanding success in the treatment of stomach ulcers,
bismuth has been enjoying the rapidly growing attention of physicians
and pharmacists. Whether in tablet form, as a suspension, ointment
or suppository, bismuth-based medicines can be found in a multitude
of households today.

Cosmetics
When adding that final touch to a particular makeup, it is
often bismuth that is used, for instance in eye shadow made
out of bismuth oxychloride. Other cosmetics such as nail varnish
and lipstick also shine out thanks to their characteristic metallic,
shimmering, mother-of-pearl effect.
