Abstract
A metal borate production method is realized by the reaction, M(NO3)+Na2B4O7.10H2O→M.B2O3. nH2O+NaNO3+nH2O, between borax and perchlorate or nitrate solution comprising a metal, or another completely dissolved metal salt in stochiometric proportion and the synthesis of nano-structured metal borates having antibacterial characteristic without addition of a second. solvent or additive substance to the medium.
Claims6
A metal borate production method, wherein a reaction between borax and perchlorate or a nitrate solution comprising a metal is conducted by the following equation:
- M(NO3)+Na2B4O7.10H2O=M.B2O3.nH2O+NaNO3+nH2O
- the metal borate production method is realized in a stoichiometric proportion and a synthesis of nano-structured metal borates having antibacterial characteristic without addition of a second solvent or additive substance to a reaction medium, and comprises the following steps:
- adjusting reactive amounts of metal perchlorate or the nitrate solution and a borax compound to be at a value between 1:1 and 2:1 by mole in a manner compliant to a reaction stoichiometry;
- adding the borax compound to the metal perchlorate or the nitrate solution with adjusted amounts and applying a mixing process at a value between 25 rpm and 250 rpm;
- conducting the reaction for at least 2 hours at a fixed temperature to obtain precipitation;
- applying washing, filtration and drying processes to the precipitation obtained as a result of the reaction to obtain a final product;
- applying a sintering process the final product between temperatures 400° C. and 1500° C.
