Xenon flash lamp sintering

There is huge market demand for ceramic sintering solutions that can provide targeted direct high temperature heating, without requiring contact with the sample. Example applications include sintering fragile structures such as films, parts which are prohibitively large to heat, or layered structures with thermally sensitive layers that cannot withstand typical sintering temperatures.

Xenon flash lamps with a broad emission range (ultraviolet to infrared), also known as xenon flash, have considerable potential thanks to their large heated area size of 25 mm to over 300 mm.

This case study outlines the trials that were carried out to validate the positive results demonstrated in literature, while also investigating the potential for sintering higher temperature non-oxide ceramics, and identifying potential challenges for industrial implementation of xenon flash sintering of ceramics.

The work was undertaken at The AMRICC Centre on behalf of Lucideon and Excelitas Technologies, and was supported and partly funded by UK Research and Innovation through the Strength in Places Fund Programme.
