Why We Switched to IR Heating for CNTs

Making carbon nanotubes is all about the heat. To get chemical vapor deposition (CVD) to actually work, you need a very specific thermal gradient. For a long time, the go-to was the traditional resistive furnace. But honestly? Heating up an entire oven chamber just to get a small substrate hot is a massive waste of energy. That’s why we started using infrared (IR) heating lamps.

Cutting the Waste

Here is the thing about IR lamps: they don’t bother heating the air around them. They use radiation to hit the substrate directly. When you’re growing CNTs, you want that catalyst to hit its activation temperature now. With short-wave IR, we’re talking seconds. It’s fast. Really fast. And that changes the whole math of the process. Since you aren’t spending hours warming up the machine’s outer walls or the air inside, your kilowatt-hours per batch plummet. It’s a much cleaner way to work, and your carbon footprint actually shrinks.
