Mittejuhtiv

Mittejuhtiv refers to a property of materials that do not conduct electricity or heat well. This is in contrast to conductive materials, which allow electricity or heat to flow through them easily. Non-conductive materials are also known as insulators. The term "mittejuhtiv" is derived from Estonian and translates directly to "non-conducting."

The behavior of materials in terms of conductivity is explained by their atomic and electronic structure. In non-conductive materials, the electrons are tightly bound to their atoms and are not free to move throughout the material. This lack of free electrons prevents the flow of electric current. Similarly, the vibrations of atoms, which transfer heat, are also less efficient in non-conductive materials.

Examples of common non-conductive materials include rubber, plastic, glass, wood, and ceramics. These materials are essential in many applications where the prevention of electrical current or heat transfer is required. For instance, rubber and plastic are used to insulate electrical wires, preventing shocks and short circuits. Glass is used in windows to reduce heat loss from buildings. Wood is used in handles of cookware to prevent burns. Ceramics are employed in high-temperature applications where insulation is critical. The effectiveness of a material as a non-conductor is often measured by its resistivity, with higher resistivity indicating better insulating properties.
