Odpowiednia zawartość SiO2 w dymie krzemionkowym dla zastosowań materiałów ogniotrwałych zazwyczaj waha się od 85% Do 96%.

High-SiO2 silica fume

This type contains 90% Do 96% SiO2. High-purity silica fume is preferred because it enhances the properties of refractory materials, such as improving their strength, trwałość, and resistance to thermal shock and chemical attack. Ensuring a high SiO2 content helps achieve these desired characteristics, making the refractory materials more effective and reliable in high-temperature environments.

Lower-SiO2 silica fume

This type has a SiO2 content of less than 90%. While it might offer slightly less strength and refractoriness compared to the high-SiO2 variant, it can sometimes be preferable due to factors like cost or workability.

Ultimately, the most suitable SiO2 content depends on the specific requirements of your refractory application. Consult us to determine the best option for your project.
