Thermal analysis of a bioglass yields a curve whose function

Thermal analysis of a bioglass yields a curve, whose function is given by the function V9T). describe step by step, how you would determine the Tg.

Solution

The Tg canbe found from the DSC curve and is located where the curve shows deviation frm the linear trend.

The curve where the softening takes place is where the Tg occurs, but there is a choice of where to take the Tg, some take it at the start, others take it inthe tranition and others at the end. Intersectio of the tangents from lower trend and intermediate trend is also used.
