4inch Single Crystal Quartz Wafer 42Y Cut Double Side Polish
Quartz crystal is currently the most used crystal and is an important electronic material. When a quartz wafer cut in a certain direction is subjected to mechanical stress, an electric field or charge proportional to the stress will be generated. This phenomenon is called the positive piezoelectric effect.
BonTek grows crystal and fabricate wafers, we are piezoelectric specialist. We work mostly with wafers and substrates made from Quartz Crystal, Lithium Niobate, Lithium Tantalate etc.
