The Effect of Addition of Al2tio5 on the Making of Al2O3 Ceramics on Physical Properties and Microstructure

Introduction

Background

Al2O3 ceramics are widely used in various industries due to their exceptional mechanical properties, thermal stability, and resistance to corrosion. However, the production of high-quality Al2O3 ceramics is often challenging due to the presence of defects and impurities. The addition of Al2tio5 has been found to improve the physical properties and microstructure of Al2O3 ceramics, making it an attractive additive in the production of high-quality ceramics.

Methodology

In this study, variations in adding Al2tio5 were carried out in a proportion of 10%, 15%, 20%, 25%, and 30% based on weight. The test and analysis results show that the optimal composition of Al2O3 ceramics occurs in a mixture of 70% Al2O3 and 30% Al2tio5, which is presented at 1500 ° C. In this condition, a density of 3.69 gr/cm³ is obtained and a very low porosity, which is 0.12%. In addition, the lowest thermal expansion coefficient value is recorded at 3 x 10⁻⁶ ° C⁻¹.
