Quartz ke thepa e ikhethang, ka lebaka la boemo ba eona bo phahameng ba bohloeki ba SiO₂ le ho kopanya thepa ea mechine, ea motlakase, ea mocheso, ea lik'hemik'hale le ea optical.

Mephato e Tlwaelehilengke JGS1, JGS2, le JGS3. 

Thepa e Tloaelehileng
boemo bo phahameng ba bohloeki ba SiO₂
botsitso bo phahameng ba mocheso o phahameng
phetiso ya kganya e hodimo.
insulation e ntle haholo ea motlakase
e babatsehang ea ho kenya mocheso oa mocheso
khanyetso e phahameng ea lik'hemik'hale

Lisebelisoa tse Tloaelehileng
bakeng sa mekhoa ea tlhahiso ea semiconductor
bakeng sa mekhoa ea tlhahiso ea fiber optical
bakeng sa ts'ebetso ea tlhahiso ea lisele tsa letsatsi
bakeng sa mekhoa ea tlhahiso ea LED
