Make Pure Silicon Dioxide

Here I show you how to make pure SiO2 powder using two relatively common chemicals. Sodium silicate can be found as water glass, which has many uses including auto repair and sealant. Sodium bisulfate is sometimes used as pH down for pools, be sure to check the label to make sure it contains bisulfate.

You could also get pure SiO2 by crushing up silica gel beads, but that might be difficult and the beads could have other additives that reduce purity.

I'll be using the SiO2 I produced in my upcoming thermite compilation video.

what camera are you using, its well good

[mrhomescientist]

@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.

@mrhomescientist How much was it? We're looking for a good camera to use as the one we are currently using has terrible focus and light pickup.

[mrhomescientist]

@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.

crack!! XD

Could you also just heat the ortho-acid in a beaker on a hot plate?

do you know how to get the report of the silicone dioxide in Indonesian market?? and the largest silicone dioxide supplier in indonesia? thanks

[HomesteadScientific]

@mrhomescientist Lapel mics work really nice, and they don't cost too much.

[danielson2k9]

is it not just quartz?

[thegodofchemistry]

what are you gonna do with it its almost insoluble in water

[mrhomescientist]

@gettingahandle Possibly. Silica and silicone are two very different things. It might be possible to make silica gel, but I'm not sure how.
