Zusammenfassung:	The method of calcining titanium dioxide comprising monitoring conversion of anatase titanium dioxide to rutile titanium dioxide by Raman spectroscopy utilizing and optical probe positioned in close proximity to a calcination kilm or coupled to equipment associated with a calcination kiln. Un método para calcinar dioxido de titanio, que comprende verificar la conversion de dioxido de titanio de anatasa a dioxido de rutilo, colocando una sonda optica cerca de un horno de calcinacion y verificando el espectro Raman producido por el dioxido de titanio. El control de la operacion del horno es mejorado ya que el método provee una retroalimentacion más rápida del grado de conversion que los métodos tradicionales, tales como fluorescencia de rayos X.
