ceramic heating element

[srolesen]

atomizer allways seem to gum up where the nichrome wire get's too hot. not too surprising since nichrome resistance only increases by 10% for 1000C increase in temperature, so when some part of nichrome wire is not suffeciently cooled it burns wick, juice and tastebuds instead of throtteling temperature.

anyone tried diff materials for atomizer like ceramics ?
or is there something in this i am missing ???


example
High temperature heaters and ceramic heating elements, hot surface igniters, ceramic ignitors from Rauschert

So what will prevent carbonizing of the ceramic element also?

This idea was kicked around a couple years ago....it seems that they arent very efficient for our use...and finding one small enough and cheap enough wasnt easy either.

because ceramics can be made self regulating so if an area of the heating surface is no suffeciently cooled it will stop heating that specific area because of internal resistance increasing in that area, as opposed to the nicrome wire where a specific area is not cooled, so it overheats untill it glows and combusts everything and my tastebuds

damn not the reply i was hoping for lol

I see what your saying....but you can regulate the temperature of a wire coil the same as any other heat source...reduce the current...increase the length of wire or use a different gauge wire...pulse the button like I do...and so on. I never let the coil get red hot.

Anything will gum up eventually after all the volatile components of the liquid evaporate...and whats left is junk that stays in the wick and on the coil.

The problem with ceramic is there is too much thermal mass sucking up the energy...so it becomes an inefficient use of battery power.

I do know what your saying though...it would be cool to have something like that...and by no means am I telling you that you shouldnt experiment with it if you want...you never know what a person can come up with something that has been "proven" worthless.

Thx lol, read thriugh that one, but has it only ever been tested once ?

i'm waiting for the ultrasonic atomizer. it's not that coils don't work. they just have a finite lifespan like lightbulbs. halogen bomex enclosed atty maybe?

i've read that ultrasonics are too big to be practical at this point. even 'jerry' from ruyan confirmed this was evaluated. still, maybe in a couple of years.

i've played with them. Sun has the smallest around (1/8th" x 1/2) but it's still a power problem - those things eat bats.

because it put out so much delicious fog you need compas to find your way, or because it waste much energy somehow ?

 

[srolesen]

if anyone is interested you can get the paste they use to make ceramic heating elements from here:
ESL ElectroScience Product Spotlight - Thick-Film Heaters Made From Dielectric Coated Stainless Steel Substrates
looks like samples are available, with recommended max of 70W/cm2 it should be able to flash heat easily

Sorry for the delay, haven't been on much this week... The standard heating cartridges are slow to heat (on bats anyway) and pull a lot of wattage. The OP at Replacement for nichrome coil... was trying to design one for the specific application in ecigs…. Shame it appears to have fizzled out.

Nice! Wonder if anyone is working this?

 

[srolesen]

lol idk, i think they should but i havent really found anything searching forum for info about it
and not a single ceramic atomizer for ecig's on the net either???
