Shape factor scherrer equation
Webb此时， Scherrer 公式适用。 但晶粒尺寸大到一定程度时，应力引起的宽化比较显著，此时必须考虑引力引起的宽化，Scherrer 公式不再适用。 我们在计算晶粒尺寸时， 一般采用低角度的衍射线 ，如果晶粒尺寸较大，可用较高衍射角的衍射线来代替。 Webb27 sep. 2024 · The grain size of the YSZ thin films was calculated using the Scherrer equation described in [ 27 ]: β θ (1) where K is the crystallite shape factor (in this work K = 0.94), is the X-ray wavelength, β is the full width at half maximum (FWHM) of the (111) reflection located at approximately 2 θ = 30°, and θ is the diffraction angle.
