Title: biggest weight to mass
Post by: healixe on April 08, 2008, 07:01:18
ive been thinking about this recently,
does anyone know what the heaviest thing to its mass is ie really small and heavy.
the one i have come up with is black hole matter but i was thinking a more easily attainable materials.
any ideas?

You mean the density? I believe it would be "Iridium". The higher the number on the periodic table, the more dense it is.

thats is what i meant :P
but is the ididum rare, expensive or radioatcive?

Pure iridium is very brittle and is nearly impossible to machine. It is primarily used as a hardening agent for platinum. Platinum-iridium alloys are used to make crucibles and other high temperature equipment. Iridium is also alloyed with osmium to make the tips of fountain pens and compass bearings.

Iridium is the most corrosive resistant metal known. For this reason, the standard meter bar was created from an alloy of 90% platinum and 10% iridium.

Neutronium is probably as dense as it gets before things drop away into alice in wonderland.... but it is still a theoretical material.

I believe synthetic materials can be made in the lab that is heavier than iridium, but its only in very small quantities, like a couple of atoms or something. :) Would have to google this a bit.

Iridium metal is hard to get, and very expensive. Mostly non-toxic due to its relative unreactivity.

Iridium costs about $500/troy ounce. (Whatever that means...)
