Diatomite based ceramics macro- and microscopic characterization

2012-03-16T11:00:57Z

A Moroccan diatomite is characterized chemically and physically. Mechanical properties of ceramics prepared by sintering at different temperatures ranging from 1050 to 1350 degrees C are studied. Compressive strength and Young modulus are determined by compression tests. Densification and evolution of the microstructure are followed by SEM and other tests.

Vallet's method of description of the wüstite subphases from the external boundaries equations of phase diagram, and the oxygen chemical potential (LogpO2(T,x)) was applied to results from the literature concerning the manganese monoxide MnOx. An equilibrium diagram between 700 and 1400°C is drawn which reveals 5 probable subphases with a main separation of the phase field at 1204°C.

Two models are elaborated of the variation of lattice parameter a as a function of composition and temperature. Factor B = BTh(Θ) + BSt(z) is modeled. An empirical relation between BTh(Θ) and a(Θ) is discussed from the point of view of Grüneisen's law. An approximate value of the compressibility can be determined. Such correlations are interesting when studying isomorphous compounds, transiti...

The equilibrium phase field is proposed for the first time to be separated into 2 main subdomains by the isothermal surface at 911°C. Above this temperature would exist three subphases Wi (i=1,2,3). Because of a more complex thermodynamic behavior below this temperature, the half empirical relation [logpO2 = (ai.T-1+ bi) x + ci.T-1 + di] is not sufficient. Some experimental evidences of existen...
