Beryllium characteristics/Thermal shock

[mjd1982]

Hi there

 

I am a very unscientific person looking for some help in identifying certain traits of Beryllium. Specifically, I was wondering whether anyone could help me with the following 2 values:

1. Thermal shock resistance

2. Thermal expansion co-efficient (perhaps in E-6/K?)

 

I am also trying to identify 2 other things: a measure of inertness, and thermal shock resistance for the following:

1. Silicon carbide

2. Quartz

3. Graphite

4. Silicon

 

I hope this makes at least a modicum of sense. If anyone could help me in any way, even by pointing me in another direction, I would be very very grateful!

 

thanks

Be coefficient of thermal expansion is 11.3 x 10^-6/K

Thanks a lot for that mate, that hhas given me a good amount of the info I need.

 

1 question about that- I have measurements for thermal expansion in "E-6/K". How does this relate to "10^-6/K". For instance I have that the coefficient for Silicon carbide is 4.6 E-6/K. How would that translate in terms of "10^-6/K"?

 

thanks

It's also interesting to note that beryllium shows slightly different characteristics from the other elements in the group.

 

Example: it does not form strong bases (like all other elements of gr I-II do), it cannot me forged like other elements in his group, it does not have metallic shine like other group elements do. And all that is due to beryllium's small radium which makes him have covalent bond rather than metallic one, changing so his characteristics from the other group members.

It's the same thing; (negative) exponents of 10. Parts per million per Kelvin.
