High-Temperature Materials

That's very hot, but you could look into quartz glass.

There's some external links there, listing manufacturers. Best bet is to contact one of them.

Hydrogels?

probably the best available

Thank you for your reply. I shall investigate.

so hight temperature withstand, and has tranparent feature?

1600-2200centidegree.

marking.

Thank you for your reply. I appreciate your help.

Origo

The data I have shows fused silica or quartz is limited to 950°C - 1750°F.

Thank you for your reply. I appreciate that you took the time to respond.

made in china. they can produce such glass from 500----1730 C /100mm thickness

other can rich to 2000c

Thank you for your reply to my question. I shall explore the information that you provided.

I would look at sapphire. What is the application?

3000°F is close to the melting point of sapphire but I can't think of a transparent material that goes higher.

Thank you for your additional reply. Initially,I should have listed additional parameters, such as being colorless, thickness not to exceed 0.5 inches, possess the ability to be cast as a machine part of approximately 16 square inches, and to be able to transmit wavelengths of 1000 to 2000 Angstroms without distortion.

That's a very tall order at those temperatures!

1000Å is into the far U.V., even quartz & sapphire are going to struggle with that.The materials that can transmit those wavelengths like magnesium fluoride or lithium fluoride won't take the temperature and are horrible materials to handle.

Again, thank you for your input. You have been very helpful. Judging from the replies that I have received, I am convinced that I shall have to try an alternative approach to the problem in order to reach my goal.

yOU CAN THINK OF CHEMICAL VAPOUR DEPOSITION COATINGS(CVD) FOR YOUR REQUIREMENTS. CVD COATINS CAN BE DONE FOR THE FOLLOWING PARAMETERS

• HIGH TEMPERATURE
• OPTICAL QUALITY
• REFLECTIVITY
• ELECTRIC CONDUCTION AND MAGNETIC/NON MAGNETIC
• CORROSION/CAVITATION
• ABRATION/EROSION ETC.......

MOST REQUIRED PARAMETERS CAN BE ACHIEVED IN CVD COATINGS

YOU CAN ALSO GO FOR NANO COATINGS

I WILL PROVIDE THE CONTACT DETAILS FOR CVD COATINGS SHORTLY

I think fused silica would be the best bet.

Hello,

I'm no engineer but this may help. There is a product called aerogel. Aerogel may have the properties you desire. Google the name or try this link: http://www.unitednuclear.com/aerogel.htm

It may be the same as others here have suggested but they called it by its proper name. I have some small samples of aerogel and it is amazing! It is so light it doesn't register with the senses as other items would. It has super insulating properties also.

Aerogel may not be a viable item. It is an insulation and I have used it for that but it is either a compacted powder or a fiber so I don't see how it could be used for and type of pressure boundary.

You still need a substrate to support the coating & the substrate has to meet the same parameters.

Welding is also one good option
