1. Piezoelectric Effect: Taim ol i kisim ol fos bilong ausait, ol 'quartz crystals' i save bungim pawa, wanpela samting ol i kolim 'piezoelectric effect'. Dispela samting i mekim na ol 'quartz crystals' i ken senisim 'mechanical energy' i go long 'electrical energy', na long dispela rot ol i ken salim na prosesim ol toksave.
2. Frekwensi Stebiliti: Osilesen frikwensi bilong ol 'quartz crystals' i stap gut tru na ol samting bilong envairomen olsem tempereja na presa i no save bagarapim tumas. Dispela i mekim ol 'quartz crystals' i kamap gutpela samting bilong wokim ol 'high-precision oscillators, na i save givim ol gutpela klok signal long kain kain ilektronik divais.
