Article
Full-text available
The synthesis and spectroscopic features of Ca3Co4O9 oxide thermoelectric materials produced by solid-state production from affordable precursors were studied in the present study. Thermoelectric and photovoltaic materials are gaining continued importance and are frequently used in industrial trading fields for renewable energy. Both materials can...

There are significant ruby formations across the world that have been commercialized. Similarly, there are many mineralogical formation regions in Türkiye with gemological features of high quality and precious stone features. However, there is not enough information in the literature about the formation of ruby in Türkiye, and its usability as a pr...

When the export values of ceramic sanitary ware in Turkey are analyzed, it is seen that the data for the year 2022 of ~660 million dollars continues to increase. In the sector, which reaches an annual average increase of 100 million dollars, the amount of production as well as the design demands change and shape the market. The most important diffi...

The use of right glaze compositions, which enable ceramic sanitary ware (such as sink, toilet bowl, toilet bowl, etc.) to have better hygienic, aesthetic and technical properties, is of great importance as in other ceramic products. Glaze compositions, which provide durability to sanitary ware materials, reduce impact resistance and give ceramic ma...
Article
This study was aimed to carrying out preliminary research in determining dopant anion and cation diffusion heat in the natural apatite structure. According to the results, it was found that the diffusion of the additive atoms between the two heat stages would increase. It was also found that for the diffusion and high relative density, the first st...

Renewable energy sources draw attention day by day and studies in this field are increasing. However, in addition to producing energy, the efficient use of the energy produced is of greater importance. Thermoelectric materials come into play at this stage, but the production of materials at the desired level in terms of efficiency is still a proble...
