Iranian Scientists Produce High Resistance Nanoceramics

Iranian scientists succeeded in synthesizing cobalt oxide-based nanoceramics with high purity, mechanical and chemical resistance at low temperatures. 
 

Given the desired mechanical, electrical, and optical properties of these nanoceramics, they have wide applications in the production of superconductors, semiconductors, dielectrics, glaze coatings, electrodes, luminescence, and magnetic materials etc.

Abdolali Alami, one of the researchers at the University of Tabriz, northeastern Iran, elaborated on the project, noting that better mechanical properties like higher strength and hardness, high surface to volume ratio (which leads to precise control over the surface), lower sinter temperature (which results in economic production and costs saving) are some characteristics of these nanoceramics.

"Better electrical, magnetic, and optical properties such as superconductivity at higher temperatures and better light transparency are examples of nanoceramics products," he reiterated.

Explaining the method used in the process of production of high resistance nanoceramics, Alami said," In this method, we first mix appropriate amounts of the required compounds with definite weight ratios, then we grind the mixture pretty enough to reach a uniform mixture."

"After adding the water, the resulting suspension is mixed, dried and powdered. The resulting powder is heated in an electric oven at a specific temperature as long as needed. Finally, it is cooled inside the oven to the room temperature."
