  1. I trust your data... Glad I joined! I definitely work with muractic acid, because I am a mason by trade and we have to use it to an our bricks, I know muractic acid and hydrochloric acid are close to the same but muractic may have some impurities. I just was wandering , if muractic acid would be good enough for my experiment? I was reading up and it definitely works better at a ph of 4. So if I am mixing small amounts, so we will go with 300ml/1 1/4cup of distilled water (I assume distilled water is ph 7??) and how many ml's of muractic acid to add to 300ml of water to get a ph of 4. S
  2. Thanks for helping, but you must be patient with me I am no chemist. So straight muriatic or hydrochloric acid will dissolve calcined alumina, so what you are saying a aqueous solution which is diluted will no harm the particles, but put a charge or barrier and keeping them de-agglomerated? So what about muriatic acid? If so how much per cup of distilled water? I am only using 1/8 tsp of calcined alumina per 0.34 oz, so does that sound like too much? Above I mentioned using a very small amount glycerin in the solution to help keep the abrasive from drying on my substrate, I so woul
  3. Hi, Not sure what a aqueous solution exactly is, but does it involve distilled water and an acid? Can I make my own aqueous solution? Sorry but I am not very familiar with chemistry, but I am interested.. Roughly do you think I got my pH to about 3-3.5 using 1/8 tsp of citric acid in a cup of distilled water? So hydrochloric acid will dissolve the Calcined alumina?
  4. I have a sample of very fine abrasive powder from a company, and I am trying to figure out how to suspend it and disperse it onto my substrate. I have a probe sonicator, for agitating, but I can't find out what the appropriate liquids would be . I have tried ethanol, but when it dries it agglomerates again. I am not wanting it totally wet in a slurry, but I want it to stay 'somewhat' tacky/intact were I spray it. Based on my reading this type of Calcined alumina works in a acid environment, of about 3.5 - 4. I tried an ethanol 80% to 20% glycerin and it seemed to be the most effec
