SCHOTT Technical Glasses

Foreword
Apart from its application in optics, glass as a technical material
has exerted a formative influence on the development
of important technological fields such as chemistry, pharmaceutics,
automotive, optics, optoelectronics and information
technology. Traditional areas of technical application for
glass, such as laboratory apparatuses, flat panel displays and
light sources with their various requirements on chemicalphysical
properties, have led to the development of a great
variety of special glass types. Through new fields of application,
particularly in optoelectronics, this variety of glass
types and their modes of application have been continually
enhanced, and new forming processes have been developed.
The hermetic encapsulation of electronic components
has given decisive impetus to development activities. Finally,
the manufacture of high-quality glass-ceramics from glass
has opened entirely new dimensions, setting new standards
for various technical applications.
To continuously optimize all commercial glasses and glass
articles for existing applications and develop glasses and
processes for new applications is the constant endeavor
of SCHOTT. For such dynamic development, it is essential
to be in close contact with the customers and to keep them
as well informed as possible about glass.
SCHOTT Technical Glasses offers pertinent information in
concise form. It contains general information for the determination
and evaluation of important glass properties and
also informs about specific chemical and physical characteristics
and possible applications of the commercial technical
glasses produced by SCHOTT. With this brochure, we hope
to assist scientists, engineers, and designers in making the
appropriate choice and make optimum use of SCHOTT
products.
Users should keep in mind that the curves or sets of curves
shown in the diagrams are not based on precision measurements
but rather characterize and illustrate the typical
property profiles of the respective glasses or glass types.
Up-to-date characteristic values of particular glasses can
be found in the tables of this brochure or in separate data
sheets.
