Electric Resistance Single Phase Heating Element

Automotive spark plug and a laser thermometer.

"... and above" ? 5000 is above, so is 10000

"resistance heating element that can withstand 3000 degree centigrade"

Is that while the resistance heating element is energized? Or, no?

3000 and above! What is the application exactly?

You might try induction heating as an option. I believe an alumina crucible will stand that temp.

Visit testbourse.com site for heater element. Use R S thermocouple to read tempt. S D Bakare

testbourse.com leads nowhere.

I believe he meant testbourne.com. Regardless, 3000 has to be a mistake. Testbourne has tungsten heating elements but they're for vacuum vaporizing metals for thin film deposition. Highest temp I saw was 1800, and pretty sure that's for at least a partial vacuum. But thanks for almost link SK. . Pretty cool stuff there. Electron beam heated crucibles and what not.

Do you REALLY mean 3000°C? The only metals in my (probably less than comprehensive) list, that melt above 3000°C are Tungsten and Osmium.

And, what about the ancillary stuff like mounting brackets, wiring, etc.?? A little warm for those particular metals.

I would guess that induction might be the only feasible way to go with electricity....but really I have no other ideas....

Dear Mr.ropo,

I am of the view that no metal combination can with stand 3000 Deg.C, and work, and measuring also will have problem.

Quartz halogen bulbs can stand up to a tick more than 3,422 °C, and as the temperature and the colour are synonymous, a comparison of the colours in special optics between the part to measure and the bulb filament colour will give the approximate temperature.

It has been done like that for many years....for iron and steel smelting for example I believe.

What the maximum possible actually is, I have no idea.

Molybdenum Disilicide heating elements are the hottest physically solid heaters money can buy, and are rated up to 1800 °C, or 3272 °F. I don't think you can do that with any form of carbon, and you can only get near this with Silicon Carbide, as is sometimes used in some electric furnaces. Pure carbon electrodes (not in resistor mode) are used in heating mixtures of carbon and silica for silicon production in China, and also used for heating MgO/Si mixtures for the production of magnesium.

You can't get to 3000 °C with any known solid, but you might get there with some lasers, or a plasma-air furnace.

As others have indicated above please provide more information on your application.

The only methods I have experience with at these temperatures are induction heating using a fine grain graphite suscepter in an oxygen free environment or a silicon smelting furnace with operates usually between 2600 C and 3000 C.

An optical pyrometer is about the only way I know to measure 3000 c in a production environment.

thanks

Better late than never! Did you solve your problem? If so, How?
