Manufacturing and Characterization of Traditional Ceramics with Raw Materials Kaolin, Quartz, Feldspar, and Clay

Introduction

Traditional ceramics have been a vital part of human civilization for centuries, with their unique properties and versatility making them an essential material in various industries. The production of traditional ceramics involves the use of raw materials, which are mixed and processed to create a final product with desired physical, mechanical, and thermal properties. In this study, we aim to manufacture traditional ceramics using raw materials kaolin, quartz, feldspar, and clay, with a focus on optimizing their physical and mechanical properties, as well as their thermal stability.

Raw Materials and Manufacturing Process

The raw materials used in this study are kaolin, quartz, feldspar, and clay, which are commonly used in the production of traditional ceramics. Kaolin is a type of clay mineral that is rich in aluminum and silicon, while quartz is a mineral composed of silicon and oxygen. Feldspar is a group of minerals that are rich in aluminum, silicon, and oxygen, and clay is a type of fine-grained earth material that is rich in water and minerals.

The manufacturing process begins by preparing the raw materials, which involves changing their microstructure and elemental content using the SEM-EDX method. This method allows for the analysis of the raw materials' composition and structure, which is essential in determining their suitability for ceramic production.

After preparing the raw materials, they are sifted with variations in size, including 100 mesh, 150 mesh, 200 mesh, and 300 mesh. This process is crucial in determining the final properties of the ceramic product, as the size of the raw materials can affect the ceramic's mechanical and thermal properties.

Sample Preparation and Characterization

The samples are printed using a hydraulic press, with a comparison of the mixture of kaolin, quartz, feldspar, and clay, which is 20:30:30:20. After printing, the sample is left for 2 x 24 hours for the drying process before combustion in the furnace at 1000 °C for 5 hours. This process is essential in determining the final properties of the ceramic product, as the firing temperature and duration can affect the ceramic's physical, mechanical, and thermal properties.

After the combustion process, characterization is carried out to determine the physical properties (dry shrinkage and burning shrinkage), mechanical properties (hardness and compressive strength), as well as thermal and microstructure.

Characterization Results and Analysis

The results of characterization show that the highest dry and burning shrinkage values are found in the size of the raw material 300 mesh. The maximum hardness value is obtained at the same grain size, namely with a hardness value of 2,223,107 MPa. In addition, the optimum compressive strength value is also recorded on the grain size of 300 mesh with a value of 45.777 MPa. This finding shows that the grain size has a significant influence on the mechanical properties of the ceramic produced.

Through the Differential Thermal Analysis (DTA) testing, no change in shape in the sample until the heating temperature reaches 950 °C. This indicates that the ceramic produced has good thermal stability, which is very necessary for applications in high-temperature conditions.

Microstructure characterization reveals the presence of pores in ceramics formed with diameters ranging from 1,027 μm to 7.862 μm. These pores play an important role in determining the mechanical and thermal properties of ceramics. The content of the elements of the ceramic produced shows a variety of compositions, with a percentage of carbon of 3.20%, oxygen 50.86%, sodium 1.58%, aluminum 12.07%, silicon 29.43%, potassium 1.36%, and Iron 1.50%.

Research Implications

This study made a significant contribution in the development of traditional ceramic materials. It is expected that ceramic products from Kaolin, Quartz, Feldspar, and Clay can be used in various industrial applications, especially those that require materials with good mechanical and thermal properties.

By utilizing local raw materials and developing efficient manufacturing techniques, this research also has the potential to support sustainability and environmentally friendly in the ceramic industry. Further examination of other properties can be done to optimize even more specific variants according to the needs of certain applications in the future.

Conclusion

In conclusion, this study has successfully manufactured traditional ceramics using raw materials kaolin, quartz, feldspar, and clay. The results of characterization show that the ceramic produced has good physical, mechanical, and thermal properties, making it suitable for various industrial applications. The study also highlights the importance of grain size in determining the final properties of the ceramic product.

The research implications of this study are significant, as it has the potential to support sustainability and environmentally friendly in the ceramic industry. Further examination of other properties can be done to optimize even more specific variants according to the needs of certain applications in the future.

Future Directions

Future studies can focus on optimizing the manufacturing process to produce ceramics with even better properties. This can be achieved by varying the ratio of raw materials, adjusting the firing temperature and duration, or using different sintering techniques.

Additionally, the study can be extended to explore the use of other raw materials or additives to improve the properties of the ceramic product. This can include the use of recycled materials, waste materials, or natural materials to create more sustainable and environmentally friendly ceramics.
