Silicon bricks are highly versatile and lend themselves to a huge number of uses. They are both waterproof and able to withstand a large amount of heat, making them indispensable for use within refractory or forging work. This has made them popular within a large number of industries and highly sought after for their durable nature.
Many people who are working with forging find that silicon bricks work better than more natural materials for the hottest parts of their blast furnaces. This is because they are able to withstand the heat, but also able to radiate it back. This allows a better control of the temperatures within the furnace, but also helps save on fuel.
They are also much less likely to break down over time, not being prone to the same faults and cracks as other materials. The bonding process used to create them ensures that they are solid, without any flaws. This means that they can be used for a number of years without worrying about their stability. The same cannot be said for more organic materials, and those materials must be checked much more often to ensure that they are not going to crack or explode, ruining any project that was being worked upon.
They are also useful in industrial applications such as building waste incinerators. Their thermal properties help them here, and ensure that they are not going to break down under heavy demand.
Finally, they are in high demand within the aluminum industry to line tanks. This both helps them hold larger amounts at one time and ensures that the tanks will have a longer lifespan as well.
All of the applications listed will need a slightly different concentration of silicon in their formula, so it is important to check what is needed for any given usage.
