The icosahedral phase is directly transformed into the [lambda]-[Al.sub.13][Fe.sub.4]
monoclinic structure.
The occurrence of a
monoclinic packing and interactions between the slight remaining hydrogen-bonding parts was suggested from a reciprocal lattice analysis.

The
monoclinic phase fraction ([X.sub.m]) was calculated according to the method described by Garvie and Nicholson [22]:
The torsional rigidity of the
monoclinic, piezoelectric cylinder is denoted by K and it can be computed as [9,10]
Similarly, pure
monoclinic zirconia was also checked for its catalytic activity with optimal reaction conditions (catalyst: 0.1 g, time: 6 hrs, temperature: 353 K, flow of oxygen: 40 mL/min, p[O.sub.2]: 760 torr, and cyclohexanol: 10 mL).
[beta]-Quinacridone (ER-02), as it was shown by DSC study, acted as a strong nucleating agent and promoted crystallization of iPP in
monoclinic a-phase.

The Raman bands in this spectrum can be attributed either to
monoclinic or to hexagonal [La.sub.2][O.sub.2][CO.sup.3], which are commonly observed La oxycarbonate crystal phases and are generally marked as phase (Ia) and phase (II), respectively.
The remarkable mechanical properties of zirconia, already exploited in several medical and engineering applications, are mainly due to the tetragonal to
monoclinic (tm) phase transformation.
