Silicadamp voor vuurvaste materialen

Silica Fume is widely used in the production of refractory castables thanks to its ability to provide better packing. It also needs less water than sand while maintaining the same flow characteristics, making it perfect for lower-temperature sintering. Silica fume is also great for facilitating the formation of mullite, which helps make your castables even more durable.

Castables are strong and stop gases, slak, and metal from passing through it. Silica fume castables are strongest, especially in high temperatures & high densities. The more you use silica fume in your recipe, the better it is for your casting project.

Silica fume is a type of substance that can directly impact how easily it flows. The more silica content the substance has, the better it will flow. The use of low SiO2 content silica fume may cause a higher water content in castables.

The right proportion of silica fume allows the beehive lining to withstand temperatures as high as 2100°C without distortion or melting. This makes it the most common form of lining for some ovens and furnaces.
