Specifications of Professional Spherical Aluminum Oxide Powder CAS1344-28-1 for Thermal Interface Materials

This aluminum oxide powder (CAS 1344-28-1) is designed for thermal interface materials. Its special shape is key. The particles are perfectly spherical. This round shape helps them pack together tightly. Tight packing means less empty space in your TIM. Less empty space lets heat move much better through the material. Heat transfers efficiently from hot components to coolers.

We offer different particle sizes. You can choose fine powders or slightly coarser ones. This choice matters. Fine powders fit into tiny gaps well. They improve contact between surfaces. Coarser powders might work better in thicker TIM layers. Particle size distribution is controlled. This ensures consistent performance batch after batch.

The purity level is very high. We target over 99.5% Al2O3. High purity is critical. It prevents unwanted chemical reactions in your TIM. It also avoids introducing impurities. Impurities can mess up thermal conductivity. You get a clean, reliable material.

This powder boosts thermal conductivity significantly. It helps heat escape faster. This protects sensitive electronics from overheating. It extends the life of devices. The spherical shape also lowers viscosity. Your paste or gel stays easier to apply. It spreads smoothly during manufacturing. This powder works well in silicone gels, greases, and pads.

Its chemical stability is excellent. It handles high temperatures without breaking down. It resists common solvents. This ensures long-term reliability in demanding applications. You get a stable thermal solution. Performance stays consistent over time.

Applications of Professional Spherical Aluminum Oxide Powder CAS1344-28-1 for Thermal Interface Materials

Spherical aluminum oxide powder CAS 1344-28-1 is important for thermal interface materials. These materials help move heat away from hot spots in electronics. The powder is made of very small, round particles. This shape is key. Round particles pack together tightly inside the thermal paste or pad. They leave fewer gaps between them. Heat moves through the powder particles much better than through air. So the heat can flow out more easily. This lowers the temperature of sensitive parts like computer chips. It stops them from getting too hot.

Using spherical aluminum oxide powder improves thermal conductivity. Thermal conductivity measures how well heat travels through a material. Higher thermal conductivity is better for cooling. Spherical powder often gives higher conductivity than irregular shaped powders. Irregular particles don’t fit together as well. They create more spaces that trap air. Air is a poor heat conductor. The round shape of spherical aluminum oxide powder minimizes these air pockets. This creates a more efficient path for heat.

This powder is chemically stable. It doesn’t react badly with other materials in the thermal paste. It works well with silicone oils or other carrier fluids. The powder particles are also very hard. They don’t break down easily under pressure or heat. This helps the thermal interface material last longer. It keeps working well over time.

Electronics makers use this powder in thermal pastes. They use it in thermal pads and thermal gap fillers too. These products go between a heat source and a heat sink. The spherical aluminum oxide powder fills the tiny gaps. It ensures good contact. This transfers heat effectively from the hot component to the cooling device. It is a common choice for cooling CPUs in computers. It helps cool GPUs and power supplies. Many industries rely on thermal interface materials containing this powder. It provides reliable thermal management.

5 FAQs of Professional Spherical Aluminum Oxide Powder CAS1344-28-1 for Thermal Interface Materials

What is Professional Spherical Aluminum Oxide Powder CAS 1344-28-1? This is a high-purity aluminum oxide powder. Its particles are shaped like tiny balls. The CAS number 1344-28-1 identifies it. It’s designed for demanding industrial uses like thermal interface materials (TIMs).

Why is the spherical shape important for TIMs? Round particles pack together tightly. They fit closer. This creates less empty space. It means more actual powder fills the gap. More powder improves heat transfer. Heat flows better through the material. Spherical particles also flow easily. This makes mixing them into pastes simpler. It prevents clogging in machines.

How does this powder improve thermal conductivity? Aluminum oxide conducts heat well. Using more of it in the TIM helps. The spherical shape lets you add more powder. More powder means less polymer. Polymers don’t conduct heat well. So the overall material conducts heat much better. It moves heat away from hot spots faster.

What particle sizes are available? Various sizes exist. Common sizes range from a few microns to tens of microns. Smaller particles fill tiny gaps. Larger particles bridge bigger spaces. Often, a mix of sizes is used. This achieves the densest packing. It maximizes thermal conductivity for the application.

How is this powder used in Thermal Interface Materials? Manufacturers add it to polymer bases. These bases are silicone or epoxy. The powder mixes into these liquids. It forms a thermal paste, pad, or grease. The paste fills gaps between surfaces. Think of a computer chip and its heat sink. The aluminum oxide powder carries the heat across the gap. This keeps electronic components cooler.
