negative CTE ceramic material
negative CTE ceramic material
(OP)
Hi everybody!
I am new here and hope to find an answer to my question.
Wishing to improve a flame-proof ceramic compound I search a material exibiting a negative CTE in the range 20-700°c.
May be Beta Eucryptite could have this feature but I don't find a thermal diagram of it and a possible supplier.
Is there anyone that could help me?
Thank you.

Probably the best material would be ZrW2O8(Zirconium Tungstenate} the only problem is it's still a laboratory curosity.

Fused silica--slightly negative CTE up to about 200C
Zerodur--Schott Glasswerke product
ULE--Corning product
Zirconium Phosphate--SMAHT Ceramics product
beta spodumene--Morgan Ceramics GBC division product (Zeramic)
