Description
Microsilica powder, also known as silica fume, is a byproduct of the production of silicon and ferrosilicon alloys. It is a very fine powder with high silica content, typically over 90%.
Microsilica powder is used as a refractory material due to its high melting point and thermal stability. It can be added to refractory castables, gunning mixes, and other refractory products to improve their properties.
When added to refractory materials, microsilica powder can improve their:
Strength and abrasion resistance
Thermal shock resistance
High-temperature performance
Erosion resistance
Microsilica powder is also used as a binder in refractory products. When mixed with other refractory materials, it can improve their bonding strength and help them better withstand thermal cycling and high temperatures.
