Abstract

Calcium aluminate glasses are transparent to a longer wavelength than silicate gI asses. However it is well known that they are difficult to form into conventional optics due to their high tendency to crystallize. To increase the understanding of aluminate glasses a study of the effect of small silica additions on such properties as viscosity and crystallization tendency has been combined with a study of such optical properties as infrared cut-off and UVVis-NIR spectroscopy. 1.
