2019 · 9 Jan · Shift 1 · Q10

JEE MainChemistryP Block ElementsMCQ+4 / −1
The one that is extensively used as a piezoelectric material is :
  1. A
    tridymite
  2. B
    amorphous silica
  3. C
    quartz
  4. D
    mica
View written solutionFree

Correct answer: C

  1. Recall the concept of piezoelectricity

    Piezoelectric materials are substances that develop an electric potential when mechanical stress is applied. This property is shown by certain crystalline solids.

  2. Check each option

    A: Tridymite

    • Tridymite is a crystalline form of SiO2\text{SiO}_2SiO2​.
    • It is not the material commonly used extensively for piezoelectric applications.

    B: Amorphous silica

    • Amorphous silica has no long-range crystalline order.
    • Piezoelectricity generally requires a non-centrosymmetric crystal structure.
    • Therefore, amorphous silica is not used as a piezoelectric material.

    C: Quartz

    • Quartz is a crystalline form of SiO2\text{SiO}_2SiO2​.
    • It is well known for its strong and stable piezoelectric properties.
    • Quartz is extensively used in oscillators, watches, pressure sensors, and other electronic devices.
    • Hence, this is the correct option.

    D: Mica

    • Mica is mainly used as an electrical insulator and dielectric material.
    • It is not extensively used as a piezoelectric material.

  3. Conclusion

    The material extensively used as a piezoelectric material is: Quartz\boxed{\text{Quartz}}Quartz​

  4. Compare with stored correct answer

    • Derived answer: C\text{C}C
    • Stored correct answer: C\text{C}C
    • They match.
