What are numerous products and application of mica?
Applications and products of mica:
(i) Sheet mica: Mainly used in electrical equipment and applications in form of washers, spacers, tubes, sleeves etc, where high voltages should be withstood.
Widely used in high reliability capacitors because of its high dielectric strength are used in microwave window and x-ray tube applications.
(ii) Pasted mica: Prepared by bonding loose mica splittings with numerous resins and glues into the form of hard plates or flexible sheets. Pasted mica used as flat segment plate in rotary machinery and as moulding plate where complex shapes are required like commutators, v-rings and channels.
(iii) Mica tape and wrappers: used for insulating high voltage coils, motor armatures and other area of rotating machinery.
(iv) Heater plate: used in percolators and similar commercial appliances.
(v) Reconstituted mica paper: used in capacitors, high temperature transformers and motors.
(vi) Glass bonded mica and ceramoplatics: used in electronic and electrical system where insulation requirements are preferably low dissipation factor at high frequencies, a high insulation resistance and dielectric breakdown strength along with extreme dimensional stability for example telemetering communication plates, moulded printed circuitry relay spacers.
