Special Issue Information

Dear Colleagues,

Ceramics and ceramic composites are widely used in various fields of engineering and technology due to their unique properties, such as high strength, hardness, wear resistance, thermal stability, and chemical inertness. However, these materials also face some challenges such as brittleness and reliability. Therefore, the study of structure and mechanical properties of ceramics and ceramic composites is essential for understanding their behaviour under different loading and environmental conditions, and for designing and optimizing their performance for various applications. We are pleased to invite you to share your latest findings and advances in this field, and to discuss the current challenges and future opportunities for ceramics and ceramic composites.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Exploring the underlying fundamental linkages between microstructure and properties of ceramics and ceramic composites.
  • Developing innovative processing techniques such as 3D printing to achieve desired properties in ceramics and ceramic composites.
  • Investigating the effects of tailoring composition and processing parameters on the properties of ceramics and ceramic composites.
  • Exploring the change of surface and subsurface structure during conventional machining process using molecular dynamics simulations.

I look forward to receiving your contributions.

The environmental impact of clay mining can be minimized using extractive mineral circularity practices. Combining the available knowledge of the characteristics of different clays with statistical tools was a decisive step for the improved use of mining resources. Through blends, all the mined materials can be incorporated to produce quality ceramic products. This study identified two types of clay from abandoned mining areas in the southern state of Santa Catarina, Brazil. These raw materials were valued together with plastic clay, which is widely used in the region, to develop 10 different formulations using a mixture design method. The clays were characterized using average granulometric distribution, mineralogical composition, and chemical, thermal and plasticity analyses. The specimens were shaped by extrusion, dried in an oven, fired in a muffle furnace and characterized based on their shrinkage, water absorption and compressive strength values. Two clays with varying characteristics—one with low workability and the other with a high silica content—exhibited difficulties (generating defects) in the extrusion shaping process, which compromised the final quality of the ceramic paste. Results showed that incorporating up to 45% by mass of the low-workability clay resulted in an increase in water absorption. The more siliceous clay improved dimensional control; however, its use at high contents (~80%) decreased the mechanical resistance. Nevertheless, when used in controlled amounts, these clays can be beneficial to the production of blocks and bricks because they have the potential to improve some properties of the finished ceramic products.
