High temperature Definition and 77 Threads

I need to test a sodium wicking system in high temperature and agitated conditions. The experiment setup seems like it is going to be pretty complicated, however, and I need some direction on where I might get a glass set-up that I could modify. The set-up is as follows: Solid sodium pellets...

What is the present consensus about it? What do you think is the most plausible mechanism? What do you think is the highest temperature that can be attained, perhaps room temperature?

Hello, I am looking for a seal design that would seal between the end plate and cylindrical section of a pressure vessel . The vessel is made of hastelloy X and has a working pressure of 4000 psi and a working temperature of 1600 deg F. ------------- ------ ...

I am working on a project where I need a high temperature sealing element. You can see the system in the attachment. My moving object is moving linearly in a motion slot which is constructed on a sheet metal plate. But the surrounding temperature in this process is 500 C degree and there...

Hello chemists! In the classical treatment of reaction kinetics, the overall reaction rate is usually written as a constant times the concentration of species raised to some power (called the order of reaction for that species). It is impressed in high school level students that this reaction...

Does anybody know of a RTV style sealant that can handle constant temperatures in the range of 1000oF? Oh, and it cannot be copper based. Thanks.

Hi, I wanted to ask, which type of heat transfer is generally most important for the transportation of heat especially at high temperatures? Does anybody know this? I am talking about temperatures T>1000 K

Hi! I wish to design a heat pipe for high temperature (up to 1300 degree Celsius). What material can I use? What about aluminum powder? Thanks.

I think its common knowledge that the next generation of nuclear reactors are going to operate at much higher temperatures than current designs in order to get away from the Rankin cycle and take advantage of thermochemical cycles, but what is it that makes high temperature reactors (HTR)...

What is the chemistry behind high temperature corrosion , and why is the corrosion rate higher .

What is the relative velocity of two hydrogen atoms colliding head on at a temperature of 10 million Kelvin? How do you calculate this?

Hi, I want to electrically heat a uniform block of a known material to a high temperature (about 2000 K). I want to get a rough idea of how much electrical energy I need to supply to raise the material to this temperature so as to gauge what apparatus I will need. How would I go about this...

Folks, this is my first thread in this forum. I'm writing my PhD about HTR-Fuel Elements. I'm not quite sure if anyone in this forum knows about this sort of fuel which is totally different to "normal" fuel. Anyway, I'm looking for informations about research in the US (or global) what...

I did thermodynamics I and II 50 yrs. ago so help me out here. I note that high temperature and pressure steam is used in turbines and presumably the higher, the better the efficiency. My question is, is the temperature doing anything or is it only necessary to produce the high steam pressure...

Hello, frineds I have a question How is it possible to get High Temperature Supercondactor produced by laser radiation? Maybe we can irradiate a target and the producing plasma will serrle down substrate Do you have an idea?

If we build a High Temperature superconductor without Meissner effect ; So it can build energy?:confused:

I need to use this libraries with confidence. Any articles that involves benchmarking of these cross sections?

See here.

Hello, could anyone point me to some resources where I can find information about high-temperature polymers? In particular, I am interested in the theoretical aspects of typical structures and how it enables the polymers' thermal properties and possibly other properties. Processing methodology...

Hi guys, need to purchase some resisters and caps that can tolerate temperatures upto 125 deg. cel. any ideas where i can find some - or what type i should be looking for?? thanks!

This is a chapter of a book on the history, discovery, and mechanism of superconductivity all the way to the present search on the mechanism for High-Tc superconductors. http://arxiv.org/abs/cond-mat/0608368 Zz.

Hey everyone, I found this really interesting article on Technology Review about a new technology that could remove the sulpur from high-temperature fuel cells. The sulpur causes the eventual shut down of these fuel cells, but with this new technology the cells continue working and are...

please help me in cllecting information about High Temperature Superconductor motor. Are they available in the market? how effecient are they? I need to know all their details, properties, design, advanteges. Thanks all

what is high temperature material

I'm sick and running a fever. If I take an Advil and my fever goes down, I stop shivering, but as the medicine starts wearing off, I begin to shiver more. I thoguht shivering was a mechanism designed to raise you're body heat, so it doesn't make sense that when I'm running a 103.8 temperature...

Although low temperature superconducting (LTS) switches are pretty common nowadays (used in MRI magnets etc), HTS switches are far less so, in fact I'm wondering whether the one I built recently is the world's first? Does anyone know otherwise? Does anyone care? (I doubt it). Also, is this...
