Introduction
Helium is often associated with floating balloons and squeaky voices, but its role in science and industry is far more profound. As a non-renewable noble gas, helium’s unique properties—low boiling point, inertness, and high thermal conductivity—make it indispensable for cutting-edge technologies. In this article, we explore 10 surprising applications of helium that keep our world running.
1. Cooling MRI Machines: The Lifesaving Liquid Helium
Magnetic Resonance Imaging (MRI) scanners rely on superconducting magnets, which must be cooled to -269°C using liquid helium. Without helium’s ultra-low boiling point, these medical devices couldn’t function, delaying diagnoses for millions of patients.
- Key Fact
: A single MRI machine requires 1,700+ liters of liquid helium.
- Challenge
: Global helium shortages threaten healthcare accessibility.
2. Semiconductor Manufacturing: Enabling Microchip Production
The electronics industry depends on high-purity helium (99.999%) to create defect-free silicon wafers. During chemical vapor deposition (CVD), helium acts as a carrier gas to distribute heat evenly, ensuring microscopic circuits are printed accurately.

- Did You Know?
A smartphone contains chips made possible by helium.
3. Leak Detection: Safeguarding Industrial Systems
Helium’s small atomic size makes it ideal for detecting leaks in pipelines, nuclear reactors, and spacecraft. Technicians inject helium into systems and use mass spectrometers to trace even the tiniest escapes.
- Application Example
: NASA uses helium leak tests for rocket fuel tanks.
4. Fiber Optics: Lighting Up the Internet
Helium shields fiber optic cables during production, preventing air bubbles that could disrupt data transmission. Without helium, high-speed internet and 5G networks would face significant bottlenecks.
5. Aerospace: Pressurizing Rocket Fuel
In rocket engines, helium pressurizes liquid hydrogen and oxygen tanks, ensuring consistent fuel flow. SpaceX’s Falcon rockets, for instance, use thousands of cubic meters of helium per launch.
6. Welding: Protecting Precision Joints
As a shielding gas, helium prevents oxidation in TIG welding, especially for reactive metals like aluminum and titanium. This is critical for aircraft and automotive manufacturing.
7. Deep-Sea Diving: Preventing "The Bends"
Helium-oxygen mixes (heliox) allow deep-sea divers to avoid nitrogen narcosis. Offshore oil rigs and naval operations rely on this technology for safe deep-water exploration.
8. Particle Accelerators: Unlocking Physics Mysteries
CERN’s Large Hadron Collider uses liquid helium to cool its superconducting magnets to near-absolute zero, enabling groundbreaking particle physics research.
9. Nuclear Reactors: Controlling Chain Reactions
Helium’s inertness makes it a safe coolant in next-generation nuclear reactors, such as High-Temperature Gas-Cooled Reactors (HTGRs).
10. Liquid Helium in Quantum Computing
Quantum computers like IBM’s Q System One require ultra-cold environments—achieved only with liquid helium—to maintain qubit stability.
