Fused quar􏰀 containing 0-3wt% iron with a relative density of 90% has been prepared by the process of the spark plasma sintering at 1200 ° C and its optical properties were investigated.Fourier transform infrared spectroscopy results indicated a network composed of silica and absence of unreacted materials. Fused quar􏰀 shows a light transmission of 29% at a wavelength of 800 nm that by increasing the percentage of iron to 3% by weight, the amount is reduced up to 11%.
