usapyro Posted January 3, 2012 Share Posted January 3, 2012 I am a bit confused here... It appears that there is two different names for the same substance. Not sure though...http://en.wikipedia.org/wiki/Bismuth_oxide I'm trying to figure out if the Bismuth Oxide here is the same as the bismuth trioxide I currently have.http://www.uspigment.com/chemicals.shtml The pricing is a bit cheaper than skylighter...

asilentbob Posted January 3, 2012 Share Posted January 3, 2012 Did you never take general chemistry? Yes, they are the same. Link to comment Share on other sites More sharing options...

Mumbles Posted January 3, 2012 Share Posted January 3, 2012 They're the same in this case, but more than one bismuth oxide does exist. Link to comment Share on other sites More sharing options...
pyrojig Posted January 3, 2012 Share Posted January 3, 2012 They're the same in this case, but more than one bismuth oxide does exist. Makes you wonder if it can be used 1:1 . Or if the Trioxide is needed in a smaller amount to balance the mix. Link to comment Share on other sites More sharing options...

I really have no idea what you're getting at. Of the common ones, an oxide with the approximate formula BiO (bismuth suboxide) exists, as does Bi2O4. You're rather unlikely to encounter either of those however without deliberately making them. The suboxide is made by heating Bi2O3 under vacuum, and you can over do it. The Bi2O4, and other higher oxides, requires extended autoclave reactions. Link to comment Share on other sites More sharing options...

I was wondering if it made any diff if what type of oxide was used . Such as %of oxide needed to balance the mix. I guess to put it short , would a Trioxide be used in the same ratios as a suboxide? Could they be sub'd for each other other with out changing the math of the comp. ? Link to comment Share on other sites More sharing options...
Mumbles Posted January 3, 2012 Share Posted January 3, 2012 I suspect a change in ratio would be required. However, you're unlikely to ever run into a situation where that would be necessary. Like I said, you generally would have to deliberately seek out those other ones to ever get them. If you buy something generically labeled as "bismuth oxide" and it's less than $100/lb, it will be the trioxide almost without question. Link to comment Share on other sites More sharing options...

I guess it would be a similar situation for a bismuth Nitrate(or is it sub-nitrate)and sub-carbonate , being used for a crackle comp . Are these the only salts that can sub for the lead tetra-oxide comps? Link to comment Share on other sites More sharing options...

That's still more than twice the price of Red Lead.I have to admit that mixing common and proper names does get a bit confusing. http://www.seattlepo...gory_Code=RMPAC Link to comment Share on other sites More sharing options...
