The colour of haematite depends on the crystal size.
Studies have demonstrated that the defect concentrations are strongly affected (up to several powers of 10) by crystal size.
The mineral's small crystal size made determination of its optical properties difficult.
The effect of crystal size on T m is shown more clearly in figure 11.3.
This difference was not initially observed due to technical limitations, such as small crystal size.
They appear to differ only in crystal size.
This will provide a growth site and will enhance crystal size.
The frequency can be varied by selecting the crystal size and the frequency of the electric field.
The name of an igneous rock requires information on crystal size and mineralogy.
The typical growth rate is 30 cm/h and crystal size 1x10 cm.
