A summary of the latest efforts to characterize carbon black and the l
atest findings using state-of-the-art scientific instrumentation is pr
esented. Over the years, advanced studies of furnace carbon black form
ation and characterization have helped the rubber technologist to bett
er predict the performance of the end product (i.e., a tire) but still
today these characteristics are not totally sufficient and more work
is necessary to better define and describe the exact nature of carbon
black produced using the furnace process.
