Day 22 – TITANIUM.
OK – I’m going to interrupt this chemistry stuff to wish you all a HAPPY THANKSGIVING.
Well, I’m only going to interrupt A LIDDLE’ BIT.
Here is your TITANIUM TURKEY-TRACK WEDDING BAND!
Yes, I am THANKFUL for a world where TITANIUM is possible, and now fashionable for wedding bands. OK – among SOME people.
Just don’t buy any “titanium steel” wedding bands, if you’re paying more than a few bucks. Many sell for UNDER A DOLLAR EACH from the manufacturer!
For the most part, “titanium steel” is (apparently) just STAINLESS STEEL.
Some stainless steels DO have a bit of titanium in them, but typically not much. Chromium, nickel and manganese are the biggies.
However, you MIGHT be getting more titanium, but in that case, it’s even WORSE than stainless steel.
There is an alloy of SCRAP IRON and SCRAP TITANIUM called “ferrotitanium“, which is used as an easy-melting source of titanium in the STEEL INDUSTRY. It typically contains between 30% and 70% titanium, and the remainder mostly iron, plus carbon and the typical alloying metals of both iron and titanium.
Ferrotitanium is a BYPRODUCT of the manufacture of titanium products, and is part of the recycling stream for titanium.
Ferrotitanium can be used to ADD titanium to the steel, or to REACT the titanium with IMPURITIES, which are then removed as SLAG, or BOTH.
I am not certain whether low-grade ferrotitanium is being used for such rings, but I suspect it may be.
So BEWARE. Insist on TITANIUM or a SPECIFIED ALLOY if you’re paying more than FIVE BUCKS for a ring!
And if you’re buying CARBON for a GIRL, insist on DIAMOND, and not CUPID ZIRCONIA, which ain’t much better than GRAPHITE for the application. *wink*
But BACK TO TITANIUM.
Titanium is useful for a LOT of things, and one of them is DENTAL IMPLANTS.
I love this next video, because is really demonstrates how
WE ARE SCIENCE NOW.
I love that some dentist in the trenches has all this real-life knowledge of titanium performance. THIS is the heart of science, IMO.
People are entitled to their opinions – and not just the “experts”. I have learned to respect opinions based on things like personal experience, informed outsider perspective, “untainted wisdom of the beginner”, and other reasons which fly in the face of authoritarianism and elitism.
People are entitled to QUESTIONS, no matter who they are.
The answers, of course, get COMPLICATED.
And then there was THIS – the mixing of titanium and GOLD to create an alloy that is FOUR TIMES HARDER THAN TITANIUM. Whoda thunk?
So TODAY, I’m thankful for the periodic table, INCLUDING TITANIUM.
And I’m also thankful for the kiddie table, where the best questions come from.
W (DAT BE TUNGSTEN!)
(and then the engineers argue….)
