Specifications of Professional Spherical Aluminum Oxide Powder CAS No. 1344-28-1 for Thermal Interface Materials

This is spherical aluminum oxide powder. It has the CAS number 1344-28-1. This powder is specifically designed for thermal interface materials. Its spherical shape is very important. This shape helps the particles pack together densely. It also makes the powder flow easily. This is crucial for manufacturing thermal interface materials. It allows for easier mixing into thermal pastes and greases. It helps reduce the viscosity of these materials. This makes application smoother and more reliable. The powder comes in different particle sizes. You can get average sizes like 5 microns, 10 microns, 20 microns, and 30 microns. These options let you choose the best fit for your application. High purity is another key feature. The typical purity level is 99.5% or higher. This ensures consistent performance. It minimizes unwanted impurities that could affect thermal transfer. The true density is about 3.6 g/cm³. This high density contributes to better packing efficiency. Better packing means more efficient heat transfer pathways within the material. The powder offers excellent thermal conductivity. This is the main reason it’s used in thermal interface materials. It helps move heat effectively away from sensitive components like computer chips and electronic devices. Using this powder improves the overall performance of thermal management solutions.

Applications of Professional Spherical Aluminum Oxide Powder CAS No. 1344-28-1 for Thermal Interface Materials

Thermal interface materials help move heat away from electronic parts. Hot spots in electronics cause problems. These materials fill tiny gaps between parts. Heat flows better through them. Spherical aluminum oxide powder is a key ingredient in these materials. It works very well for heat transfer.

This powder has a special shape. The spherical shape lets it pack tightly inside the thermal material. More powder means less space for air. Air blocks heat. Less air means heat moves faster. The powder itself conducts heat effectively. Aluminum oxide is very stable. It handles high temperatures without breaking down. This makes it reliable.

Manufacturers add this powder to greases, pads, and gels. These are common thermal interface materials. The powder boosts their ability to transfer heat. Electronics run cooler and last longer. Overheating damages components. Good heat management prevents this. Computers and phones use these materials. So do power supplies and LED lights. Even car electronics need good cooling.

Spherical aluminum oxide powder helps thermal materials perform better. It improves heat flow significantly. This powder is widely chosen for thermal management solutions. Its shape and properties make it effective. It helps keep modern electronics running safely.

5 FAQs of Professional Spherical Aluminum Oxide Powder CAS No. 1344-28-1 for Thermal Interface Materials

Professional Spherical Aluminum Oxide Powder (CAS 1344-28-1) is a key material used in thermal interface materials. Here are answers to five common questions.

What is spherical aluminum oxide powder? It is a fine, white powder. It comes from aluminum oxide. The particles are round. This shape helps the powder mix well. It improves performance in thermal pastes and pads.

Why use this powder in thermal interface materials? It moves heat very well. Heat needs to go from hot parts, like computer chips, to coolers. This powder helps move that heat away. It fills tiny gaps between surfaces. Heat flows better through it than through air.

What makes spherical particles better? Round particles pack together tightly. More powder fits into a small space. They also slide past each other easily. This makes the thermal paste or pad smoother. It spreads thin layers well. Heat transfers more efficiently this way.

What specifications matter? Particle size is important. Smaller particles fill gaps better. Larger sizes might flow easier. Purity is critical. High purity powder conducts heat better. It has fewer impurities blocking heat flow. Surface treatment can help the powder stick to polymers.

Is it safe? This powder is generally safe for industrial use. Handle it carefully. Avoid breathing the dust. Wear protective gear like masks and gloves. Store it properly. Keep it dry. Follow the manufacturer’s safety instructions.
