Problem Statement Project Description: Design and build a Flash sintering machine. Successfully Flash sinter a sample or samples of ceramic material. Record sample’s temperature in real time. Test the sample’s mechanical properties.

Problem Statement Motivation and Goals: Control or eliminate undesirable reactions to high temperatures. Reduce harmful and unwanted waste. Investigate the Flash sintering mechanism.

Literature Survey Sintering: Inter - particle pores in a granular material are eliminated by atomic diffusion. Sintering Driving Force: The curvature of the particle surface An externally applied pressure Chemical reaction

Literature Survey Sintering Types: Pressure Assisted Sintering. Hot Pressing. Microwave Sintering. Field Assisted Sintering

Literature Survey Field Assisted Sintering: Use of a DC electric current in the sintering process cause retardation in growth grain. Ceramics could be sintered in less than 5 seconds . Relating common used materials are: Mg-O Alumina, SiC, and ZrB2.

Literature Survey Joule Heating: Increment in the sample temperature from the scattering of electrical energy. Assumes the sample transmits radiation like a dark body.

Flash Sintering Mechanism Joule Heating: Volumetric thermal expansion caused by increase in temperature.

Related Standards International Organization for Standardization: ISO has published more than 19500 International Standards covering almost every industry.
