Light transmission of aluminium oxide

The ceramic material aluminium oxide, also known as alumina, is completely opaque, translucent or transparent – depending on the structure, and therefore on the manufacturing process. Light scattering is the keyword here. Most alumina products are made out of pure aluminium oxide powder with a well defined grain size. These powder particles are getting close(r) […]

Traditional and advanced ceramics

Clay is the most important raw material for traditional ceramics such as bricks, tiles, sanitary ceramics and tableware. The word ‘earthenware’ for ceramic pots and jugs is an indication that their raw materials are literally obtained from the ground. Clay is a natural product whose composition varies. Clay particles are flat hexagonal plates with a […]

Research in advanced ceramics – 2015

On April 30, 2015 – formerly known as the Queen’s Birthday – the Dutch Ceramic Society NKV organised a meeting in the city of Nijmegen in the Netherlands. Part of this meeting was ‘Research in advanced ceramics’, where a total of six PhD and MSc students of Dutch universities took the opportunity to present their […]

Molecular dynamics computer simulations of yttria-stabilized zirconia

Computer simulations on an atomic or molecular scale give a direct link between the microscopic details of a system (atomic masses, molecular geometry, etc.) on the one hand, and macroscopic properties that are of experimental interest (energies, transport coefficients etc.) on the other. By comparing the outcome of the simulation with experimental results, understanding can […]

PZT – the most commonly used piezoelectric material

Piezoelectric materials have the capability to convert electrical energy into mechanical energy, and vice versa. Piezo stems from the ancient Greek πιέζειν (piezein), which means ‘to press’ or ‘to squeeze’. Piezoelectric materials are among these ‘invisible’ materials that are widespread around us, although they are unknown to the public at large. Mobile phones, automotive electronics, […]
