Decomposition Temperature - DTMP
This test procedure was employed in the Foresight Ceramic Database and now is available for those having an account at Insight-Live.com.
Accumulating test data using the variables defined in these procedures enables us to create tools that enable you to compare the physical properties of materials and recipes.
While the ultimate decomposition achieved in ceramics is melting, many materials change their physical form in other ways prior to melting when they reach certain temperatures (i.e. the loss of crystal water, burning away of organics). Some materials go through multiple decompositional changes, each having its own chemistry.
Enter the temperature or range and a label for the event, for example:
245C: water of crystallization driven off
VAL - Value (V)

Decomposition is the breaking of inter-molecule bonds during melting in the kiln. To understand it we need to understand elements, oxides, compounds, solutions and mixtures (from the chemistry jargon point-of-view).
"Elements" are one kind of atom which cannot be broken down any further (except b...
