Since the acquisitions of Baehr and Expert System Solutions, two manufacturers of dilatometry equipment, TA Instruments has continued to invest in dilatometry. Most recently, the company introduced three new lines of mechanical and optical dilatometers well-suited for the ceramic industry: DIL 830, ODP 860 and DIL 820.
During firing, a glaze applied on a ceramic body undergoes several transformations, including water loss from the clay components, glass transition and softening. During the softening phase, the glaze starts to melt, giving rise to a continuous liquid layer.
