Manufacture of Cordierite Porous Ceramics (2MGO. 2AI2O3, 5SIO2) as a Gas Filter Material

Introduction

The demand for efficient and sustainable gas filter materials continues to increase, driven by the need for cleaner air and water. Cordierite, a mineral with the chemical formula 2MGO.2AI2O3.5SIO2, has emerged as a promising gas filter material due to its exceptional properties, including high temperature resistance, chemical stability, and porous ability. This study examines the potential for manufacturing cordierite porous ceramics using local raw materials, namely MgCO3, γ-Al2O3, and SiO2, as a gas filter material.

Background

Cordierite is a mineral that has been used in various applications, including ceramics, glass, and refractory materials. Its unique properties make it an attractive material for gas filter applications. The manufacturing process of cordierite porous ceramics involves several stages, including milling, drying, filtering, calcination, and sintering. The addition of wood powder (SK) with a particle size of less than 100 mesh is used to increase the cordierite ceramic porosity.

Materials and Methods

The raw materials used in this study were MgCO3, γ-Al2O3, and SiO2. The milling process was carried out using a ball mill for 48 hours, followed by drying at 110 ° C for 24 hours and filtering to pass 200 mesh. The raw materials were then calculated at 1200 ° C, based on the thermal analysis using TGA/DTA. The stages of calcination produced cordierite powder with an average particle size of around 7.78 µm.

To increase the cordierite ceramic porosity, wood powder (SK) with a particle size of less than 100 mesh was added to the cordierite powder with a concentration variation of 10%, 15%, 20%, 25%, and 30%. The mixture was then printed and presented at various temperatures, namely 1200 ° C, 1250 ° C, 1300 ° C, and 1350 ° C.

Results

The characterization results showed that the cordierite porous ceramics produced had density ranging from 0.75-1.17 g/cm3, porosity 58-63%, broken power 0.5-2 MPa, Hard (HV) 0.3-1.8 GPA, and thermal Expansion Coefficient (2-5) x 10-6 ° C-1. XRD analysis showed that the dominant phase formed was Cordierite with the Orthorombic crystal system, while the minor phase was Mullite (Orthorombic crystal system) and corundum (trigonal crystal system).

SEM observations showed that Cordierite porous ceramics had a pore size of about 10-100 µm with a relatively uneven distribution of particles. The results showed that the optimum composition was 20% of wood powder (SK) and a sintering temperature of 1250 ° C, producing a relatively uniform pore size and smaller than 50 µm.

Discussion

This study demonstrates the great potential of using local raw materials for the manufacture of cordierite porous ceramics as a gas filter material. By optimizing the composition and sintering process, cordierite porous ceramics can be produced with the appropriate characteristics for gas filter applications. The use of local raw materials can also help reduce dependence on imported materials and encourage local economic growth.

The advantages of cordierite porous ceramics as a gas filter material lie in their ability to withstand high temperatures and good chemical stability. High porosity allows smooth and effective gas flow in the filtration process.

Conclusion

In conclusion, this study has shown the potential of manufacturing cordierite porous ceramics using local raw materials as a gas filter material. The results have demonstrated that the optimum composition and sintering process can produce cordierite porous ceramics with the appropriate characteristics for gas filter applications. Further research is needed to optimize the process of making Cordierite porous ceramics and evaluate its performance in the gas filter application.

Future Research Directions

Future research should focus on optimizing the process of making Cordierite porous ceramics and evaluating its performance in the gas filter application. Factors that need to be considered include pore surface characteristics, corrosion resistance, and filtration efficiency of various types of gas.
