POROUS MATERIALS GROUP

School of Engineering
University of Liverpool


The Porous Materials Group conducts research on the manufacture and characterisation of particulate and porous materials. Our current focus is to develop the patented Lost Carbonate Sintering (LCS) process for manufacturing porous metals, to study the mechanical, thermal, electrochemical and acoustic properties of porous metals and metal matrix syntactic foams, and to explore their feasibility for applications in energy, automotive, defence, aerospace and building industries.

The LCS technology has been licensed to Versarien plc, a high-tech start-up company founded in 2010 and floated on the London Stock Exchange in June 2013, to commercialise the LCS process for micro-porous copper in thermal management applications. LCS porous copper products can be purchased from Goodfellow.
