What are other properties of this material, such as hardness at high temperature? Where to get such information?

Any more info?[edit]

This article seems pretty short. Does it have any uses? Is there any more info on it, like when it was discovered? —Preceding unsigned comment added by 70.216.49.55 (talkcontribs) --Leyo 08:30, 29 August 2008 (UTC)

Formula[edit]

The article gives the formula for THC(!) as formula TaxHf1-xCy, which seems to imply that if there are 3 atoms of Tantalum, there should be (1-3 =)−2 atoms of hafnium, an ovbious impossibility. The article then goes on to describe an "alloy" whose formula doesn't match the first one, either. Should that first formula read "TaxHfyCz, where z = x + y"? Something else? --Piledhigheranddeeper (talk) 20:19, 6 May 2011 (UTC)

I would believe this is just a typo and the formula was intended to be written as TaxHfy-xCy --Kaomie —Preceding unsigned comment added by 68.227.207.20 (talk) 22:15, 6 May 2011 (UTC)

Not a typo but a convention (x is not an integer but is less than 1). It is often used to mean that Ta+Hf=1, though I admit this is irrelevant here because y is variable (though <1). Materialscientist (talk) 01:41, 7 May 2011 (UTC)
