Hot-pressing and the alpha-beta phase transformation in silicon nitride
The kinetics of the alpha-beta transformation, the greater part of which occurs after densification is complete, are described by a first order reaction; the dependence of rate on the quantity of additive (MgO) and on temp. is similar to that found for densification, and a similar controlling mechan...

| Zusammenfassung: | The kinetics of the alpha-beta transformation, the greater part of which occurs after densification is complete, are described by a first order reaction; the dependence of rate on the quantity of additive (MgO) and on temp. is similar to that found for densification, and a similar controlling mechanism is believed to be responsible for the two processes. |
