I stand corrected - Titanium vs. Lava

My kids talk about hot lava all of the time. They plan games where they are avoiding imaginary hot lava, they threaten to burn each other with hot lava and ask me way too many questions about hot lava. I am sick of hearing about hot lava, even my friends are sick of hearing about hot lava. The most recent debate is a scientific question. I'd like to use my blog to publish my "findings" on this subject.

Andrew believes Titanium is the strongest thing in the universe, second only to God. As such he is convinced titanium is impervious to hot lava. I was certain that hot lava would win this match-up, I stand corrected. Hot Lava would NOT melt Titanium. I should have known better than to argue a scientific point with Andrew.




Titanium vs. Lava – Titanium wins!

How hot is lava?
Lava is extremely hot. Lava can reach temperatures of about 1,250° Celsius. The lava of the Hawaiian volcanoes reach these temperatures. Normal lava temperatures reach 750° Celsius. That is still much hotter than your oven is capable of reaching.

Titanium has a high melting point of 3135°F (1725°C). This melting point is approximately 400°F (220°C) above the melting point of steel and approximately 2000°F (1100°C) above that of aluminum.

Thanks for the post, my kiddos are crazy about lava the same way yours were in 2009 and your post cleared it up on the hot lava vs titanium discussion still going strongly 10 years later for another family who knew ;)
