In a mica resistor, the resistive material itself is made up of alloys like nichrome which is wound or mounted upon mica which acts as insulator for mounting. Mica is used in resistors of high rating. Hope this helps. read more

The resistor is then painted to seal the core. Metal Film Resistor. A metal film resistor is built in a very similar way. The core of this resistor is crafted from ceramic. This part, as in all resistors, is machine made. In a metal film resistor, the track is made from a metal oxide material. This has semi-conductive properties, similar to carbon. read more
