An Investigation on Injection Moulding of Seydişehir Alumina

Abstract

The utilization of alumina based ceramics has increased in our country. Alumina must have some specific characteristics for production of advanced ceramics. Physical and chemical propertes of Seydişehir alumina make it non-ceramic grade raw materials. The aim of this study is to find out process conditions for production injection moulded ceramics from Seydişehir alumina powders. This study essentially consists of characterisation, improvements of properties, injection moulding and sintering. X-ray diffraction analysis, water absorption, apparent porosity, bulk density and three point bending tests were applied to the sintered samples Physical properties of the products were greatly affected by sintering temperature

Investigation on Sintering Behaviour of Sol Gel Coated Seydişehir Alumina with TiO2

“…Alumina is a known ceramic material because of its high temperature stability, chemical inertness, strength, hardness, tribological, electrical and optical properties. The properties of alumina-based ceramics depend on the final microstructures which are affected by the characteristics of the starting powders [1][2][3][4][5][6][7]. Seydişehir Alumina has large particle size distribution and high impurity content.…”

“…Seydişehir Alumina has large particle size distribution and high impurity content. In recent years, many researchers focus on improving its sinterability properties by reducing the Na content, grinding and ceramic coating [2][3][4].…”

Investigation of the Production of β-Al₂O₃ Solid Electrolyte from Seydişehir α-Al₂O₃

“…For these reasons, studies focus on improving the quality of Seydişehir alumina powder and developing the sintering properties for the utilization of Seydişehir alumina in technical fields. [1,2].…”
