| | Filter Sintering |
| | Abstract | This project includes the utilization of electro pulsing to optimize the |
| | production of ceramic filters, specifically Yttria-Stabilized Tetragonal |
| | Polycrystalline Zirconia (3Y-TZP). Due to the versatility of this ceramic, |
| | pore sizes can be controlled to filter out particulates, bacteria, viruses, |
| | and other pathogens. However, current ceramic sintering processes |
| | require long sintering times and extensive energy costs when heating |
| | furnaces at high temperatures. Furthermore, current ceramic water |
| | filters are unable to attain the miniscule pore sizes required to filter |
| | viruses. This study sought to shorten sintering time, reach a target pore |
| | size of 20 nanometers, and achieve full density. The sintering process |
| | was optimized by varying voltage, duration, and electro pulsing |
| | frequency. At 40V, 10 microsecond pulses, and 70 Hz at 1400°C for |
| | 3000 minutes, the microstructure data showed that the pore size did |
| | achieve 20 nanometers and full density. Activation energy of space- |
| | charged clouds increased to slow the grain growth, which allowed full |
| | density at a smaller pore size. In addition, the sintering time was |
| | decreased from 7200 minutes to 3000 minutes, making the process |
| | very cost-effective. The use of electro pulsing to produce ceramic water |
| | filters is an efficient method and allows for potable drinking water to be |
| | more accessible. |
