Summary on Grant Application Form |

A feasibility study will be carried out to investigate pulsed electrostatic atomisation leading to the development of a new printing device for manufacturing engineering ceramics in the first instance and several other areas of commercial interest such as reprography, pharmaceuticals and geology. Our research in the cone-jet mode electrostatic atomisation of ceramic precursor solutions and ceramic suspensions has shown that pulsing of the applied voltage allows us to call droplets of liquid systematically and when required. This is very advantageous as up to 10 micro-metre size droplets can be obtained from a 200pm diameter nozzle, eliminating nozzle blockages and improving resolution in comparison with direct ink-jet printing. A range of liquids of different viscosities including well-dispersed zirconia suspensions will be prepared, characterised and used in electrostatic atomisation investigations. In this study we firstly intend to construct high voltage pulsing switches in order to investigate this phenomenon as a function of viscosity. Secondly, we shall input more sophisticated and controlled electric pulses via a computer. The jet, droplet and relic characteristics of such pulsed electrostatic atomisation will be studied using recorded information and electron microscopy.
