In this study, the effects of perlite addition on mechanical properties and wear resistance of alumina ceramics were investigated. Alumina powders including perlite 5%, 10%, 15%, 20% and perlite free were prepared. These powders were shaped as rectangular by using uniaxial pressing system under the load of 100 MPa. The samples were sintered at 1400°C-1550C for 2 h and were subjected to some mechanical...
