Mica has such poor electrical conductivity that it has often been used as an insulator. The resistivity of mica ranges from 1x10^12 to 2x10^14 Ω/cm depending on the type of mica. For reference, copper, a good conductor, has a resistivity of only 1.68×10^−8 Ω/m or 1.68x10^-10 Ω/cm.
no, it is an insulator.

Is mica a good electrical insulator?
First AnswerYes it is and it can also withstand heat. For many years mica was used in toasters to make a framework to hold the heating elements.Next AnswerActually mica is a very good electrical INSULATOR, but is a good THERMAL conductor, which is why it was used for holding heating elements.
Is mica a ceramic insulator?
Mica is a naturally occurring mineral with excellent insulating properties due to its structure and composition. While it is not considered a ceramic material, it is commonly used as an insulator in electrical and thermal applications due to its ability to withstand high temperatures and resist electricity.
Is mica conductor?
Mica is not a conductor of electricity. It is actually an insulator, meaning it does not allow electricity to flow through it easily. Mica is often used in electrical and electronic applications as an insulating material to prevent current flow.
What mineral is often used as an insulator i electrical equipment?
Mica is often used as an insulator in electrical equipment due to its excellent dielectric properties and thermal resistance. Its layered structure allows it to withstand high voltages and temperatures, making it ideal for applications such as capacitors, transformers, and circuit boards. Additionally, mica is chemically stable, which enhances its durability in various environments.
Which mineral has a hardness of 2.5-3 and makes a good electrical insulator?
The mineral with a hardness of 2.5-3 and that also functions well as an electrical insulator is gypsum. Gypsum is a soft mineral that can be easily scratched with a fingernail and is used in various industries for its insulating properties in electrical applications.
