78sharpshooter Posted March 17, 2014 Share Posted March 17, 2014 Getting ready to redo my 2 propane forges so I wanted to make an ITC-100 like coating and saw Dave Hammers video using the colloidal silica and zirconium silicate mixture. When I once used ITC-100 it was quite gritty and had black flecks in it so I was thinking there might be some silicon carbide in there so I was considering mixing it into the Kaolin/Zircon final coating and wondered if anyone has tried it. I did find this research article on Silicon Carbide coating of ceramic fibre useful but was looking for more recent experience http://qirt.gel.ulaval.ca/archives/qirt2008/papers/06_02_08.pdf Quote Link to comment Share on other sites More sharing options...
Frosty Posted March 18, 2014 Share Posted March 18, 2014 Nope, ITC-100 is kaolin and zirconium sand, no carbides, silicon or otherwise. Frosty The Lucky. Quote Link to comment Share on other sites More sharing options...
78sharpshooter Posted March 18, 2014 Author Share Posted March 18, 2014 Is the emissivity of zirconium sand higher than silicon carbide? Quote Link to comment Share on other sites More sharing options...
Frosty Posted March 18, 2014 Share Posted March 18, 2014 Emissivity? All I can say is I don't believe ANYBODY is putting silicon carbide in kiln washes. But go ahead, give it a shot and let us know how it works. Frosty The Lucky. Quote Link to comment Share on other sites More sharing options...
78sharpshooter Posted March 19, 2014 Author Share Posted March 19, 2014 I mixed the kaolin and zircon and it looks nothing like Itc-100. Where do the black specs in Itc-100 come from? I did find a patent that utilizes silicon carbide and compares their formulation to chamotte. http://www.google.com/patents/US4469721 Quote Link to comment Share on other sites More sharing options...
