Microheater

Article summary

Microheaters are small high-power heaters, with precise control, that can offer temperatures in excess of 1000C, even up to 1900C. Microheaters provide for accurate high temperature control, for example in electron microscopes, pressure-anvil cells or for enhancing fiberheaters. Generally speaking, the heating method for microheaters involves conversion of electrical work to high density heat. With the increase in the temperature demanded, microheater heating materials change from metallic (non-brittle GAXP) to metal-ceramic like materials (MoSi2) which tend to be brittle. With an increase in usable temperature, microheaters need to be supported or enclosed with very high thermal-resistant ceramic materials often made from small grain, high purity aluminum oxide.…
