Abstract
This work proposes the use of experimental design for optimization of microwave-assisted digestion of bio- morphic ZrO2-ceramic. Cedar wood is used as template and it was infiltrated with ZrO2 via sol-gel process. XPS, SEM and XRD have been used to verify the effectiveness of the synthesis. The effects of different combination of acids in the digestion of this sample have been optimized taking as response the concentra- tion of several metallic ions measured by ICP-MS.
Highlights
Sol-gel processing is a new technology that is being developed more quickly for the manufacture of ceramic and glasses
Cedar wood is used as template and it was infiltrated with ZrO2 via sol-gel process
The optimum mixture of acids was obtained by means of the ICP-MS and taking as response variable the concentrations of several ions to select the better mixture of acids
Summary
Sol-gel processing is a new technology that is being developed more quickly for the manufacture of ceramic and glasses In the ceramics, this method allows the uniform and fine particle formation of high purity to relatively low temperatures. This method allows the uniform and fine particle formation of high purity to relatively low temperatures These dusts can be sintered until obtaining to a high density with their corresponding good mechanical properties. The phase disperses “sol” becomes a rigid “gel”, which, as well, is reduced until its final composition by means of diverse heat treatments. A key advantage of the process sol-gel is that the product the forms initially by means of this procedure of liquid phase can be roasted to lower temperatures, compared with those of the conventional processes for ceramics
