5 FAQs of 70um Spherical Aluminum Oxide 99.95% Alumina Oxide Powder Al2o3 for Thermal Interface Materials

70um Spherical Aluminum Oxide Powder FAQs

What size is this aluminum oxide powder?
This powder is 70 micrometers average particle size. Precise size control is essential. It ensures the powder fits well into tiny gaps in thermal interface materials.

Why is the spherical shape important?
Spherical particles flow much better. They pack together more densely than jagged or irregular particles. This dense packing creates more direct paths for heat to travel through the material. Heat moves faster.

How pure is this alumina powder?
This powder is 99.95% pure Al2O3. High purity is critical. Impurities can interfere with heat transfer. Impurities might also cause unwanted chemical reactions inside electronic devices. Pure alumina avoids these problems.

How does it improve thermal conductivity?
The powder itself conducts heat well. Adding it to thermal pastes or pads increases their ability to move heat. The spherical particles touch each other efficiently inside the material matrix. Heat flows directly from particle to particle. This reduces the thermal resistance significantly.

Why choose spherical over irregular alumina powder?
Spherical powder mixes easier into polymers or silicone bases. It creates a smoother paste. This paste spreads thinly and evenly over surfaces. Irregular particles can make the paste thick and hard to apply. Spherical powder gives lower viscosity and better performance. It fills microscopic gaps more effectively between heat sources and heat sinks.
