Introduction

Ceramics

Alumina (Al2O3), a kind of 3D printing material, is one of the most important oxide ceramic materials and is characterized by high levels of hardness as well as good corrosion and temperature resistance. Components made from alumina are electrically insulating and puncture-proof and are therefore suitable for a wide range of applications, such as substrates in the electronics industry, thread guides in textile engineering, protection in thermal processes and many others. LithaLox HP 500 is a high-purity aluminum oxide (99.99 %) with outstanding material properties. It is characterized by a high density (99.4 % relative density), a high fourpoint bending strength (430 MPa) and a very smooth surface (Ra ≈ 0.4 μm). LithaLox 350 is a high-purity aluminum oxide (99.8 %) with outstanding material properties which has been developed to manufacture highly complex components with small channels and holes. Both materials can be used not only for industrial applications but also in medical engineering for permanent implants or devices due to high biocompatibility.​​
