Products made of
quartz glass contain numerous valuable properties that give them practicality
and popularity:
1) low
dielectric constant;
2) high chemical
inertness to many alkalis, acids, and salts;

4) high
resistance to thermal pulses (up to 1200 degrees Celsius);
5) a wide
spectral region of transparency among all silicate glasses, especially in the
ultraviolet part of the spectrum;
6)
nonsusceptibility to infrared and radioactive (ionizing) radiation;
7) resistance to
temperature differences; wear resistance and resistance to vibration;
8) high
mechanical strength; crystallization resistance; high uniformity of the
structure of the material.

Thanks to this set
of advantages, quartz products are a profitable and successful solution for
numerous spheres of human life and activity.
Thus, many different
elements are created from this raw material: rods, electric heaters, and
high-temperature lamps, lenses, matrices, astronomical mirrors, and microscope
lenses, viewing glasses, countertops, shelves and partitions, Durens and
Klinger glasses, semiconductor devices and thermocouples, portholes, optical
blanks (discs and plates), insulators, decor items, souvenirs and much more.
It can
be said without exaggeration that quartz products are today indispensable both
in the scientific laboratory and in industrial production, and even in everyday
life.
