IFRs, thanks.
I will try to find this reference.
About the mixtures, which I used to mill, I am suspecting that there is chemical interaction between fresh surfaces of aluminum and absolute ethanol with liberation of water. However, I could not find a reaction mechanism between these compounds.
I have attrition milled aluminum (Al) and alumina (Al2O3) mixtures in absolute ethanol. After that checked water content by Carl-Fischer titration method and revealed that it contains higher water (hydroxyl) content than those milled in ethanol which contains(5-10%)water. Water content was...
Hello,
One of suitable method for obtaining porous materials is so called selective leaching method. As may you knows a clay minerals consist from layered structure ( tetrahedral silica and octahedral alumina or magnesium). If you treat them in suitable conditions by acid or base respective...
Hi Johnrh,
Grain size of sintered ceramics can be determined by SEM. From my experience better to use thermal etching just 50-100C below those used for your sintering. Time should be no more than 1h, it is just removing grain boundary stress. Use as possible more grains and take average.
