@killerkyle2008 Thanks, my camera is an Insignia full 1080p HD camcorder, with 12x optical zoom. I'd be more specific, but there's apparently no model number for it. I think it's a Best Buy specific model.
@HomesteadScientific It was either $300 or $400, I'm not sure. I thought it was a pretty good price for the quality. My only complaint with it is the microphone isn't too great, and my videos always come out pretty quiet.
@hkparker Funny story actually, I specifically bought that crucible so I could fully replicate your bismuth crystal growing setup! Haven't gotten around to it yet though - I've been meaning to make a video about that for a pretty long time now.
@mrhomescientist oh yea! Cool. If you would be willing, we should mail each other equal amounts of bismuth and try our own methods on each others metal. At makerfaire I also talked to a nice grad student at UCLA who took some of my bismuth for analysis on one of their electron beam microscopes at some point! Looks like we'll get to the bottom of this!
@hkparker Wow that sounds awesome! Definitely let me know what he comes up with. I'd be willing to mail some bismuth around, but let me try your method and see how that works for me first. I'm going to Utah for work training next week, so I won't be posting anything else until I get back (unless I finish a video I want to do today).
You can't really take domestic/consumer products and claim they are pure. You would need to do elemental analysis using some expensive instruments. You could use a technique like ICPMS, ICPOES, XRD, or EDX. The easiest way to analize your final SiO2 powder would be using XRD to identify the phases present. Of course, our definitions of 'pure' probably differ, but in reality you can never have a 100% pure substance.
@nucleochemist Of course. Nothing can really ever be declared 100% pure, and I certainly don't have that technology available to verify. Whenever I say pure, I suppose I mean "pure enough for home lab use," since that's what really matters to me.
As a side note: while I mention commercial sources in the description, my chemicals were bought from a chemical supplier and are ACS/Reagent grade. So I can say with some confidence that my product is "pure enough" :)
@Phacias Yeah that's pretty steep! Their product will almost certainly be more pure than anything we can make at home, but really this is good enough quality for any home experimentation. As I say in the video, all the impurities from the reaction are soluble and can be easily rinsed away to give you rather high purity SiO2.
could you make silicone gel from the silicic acid. its a shame the heating method would never make large crystals. i guess you'd want a fine powder as a chemist anyway.
@eutectics About making silicone gel: I can't say for sure, but I really don't think so. Silicone is a polymer and is quite different from silicic acid (silicones include carbon atoms, while the acid has none). Research it a bit and see what you come up with!
did you ever try mixing the contaminated silicon dioxide with water then putting it on your magnetic stirring/heat plate and then gently heat the water while stirring the mixture slolwly because that should almost guarentee super high purity by allowinng the most byproduct to be released and be dissolved by the slightly warm water
@panzuman If you let it crystallise over a period of several decades, you'd get large crystals. I think that's the only way, but don't take my word for it.
Could you also just heat the ortho-acid in a beaker on a hot plate?

You can probably make a really nice lump of crystalline silicon metal with that amount of SiO2 in a thermite reaction.

I was astonished by the price of commercial SiO2 per analysis. Over $20 for 100g! Now with pure ingredients I can make my own, pure at least! ^^
