Specification of 99% Alumina 0.2- 0.5 mm 0.5-1mm Balls Alumina Bubble Ceramic Hollow

These alumina rounds come in 2 dimension varieties. The smaller sized ones determine 0.2 to 0.5 millimeters. The larger spheres measure 0.5 to 1.0 millimeters. Both kinds flaunt a high pureness level of 99% alumina. This high pureness ensures excellent performance. The material is extremely tough. It resists wear exceptionally well. These spheres manage high temperatures conveniently. They are thermally steady. This makes them perfect for severe settings.

We also use alumina bubble ceramic hollow spheres. These are made from the same 99% alumina. The production process develops special hollow bubbles. These bubbles have shut cells. This framework provides special homes. They are really lightweight. They give superior thermal insulation. They keep heat in or out efficiently. These hollow bubbles are likewise strong. They hold up against mechanical anxiety well.

These items offer many demanding applications. The alumina rounds work well as grinding media. They grind materials carefully in mills. They are made use of as driver sustains. They hold active chemicals in activators. They act as fillers in compounds. They reinforce plastics or metals. The hollow alumina bubbles excel as insulation materials. They line furnaces and kilns. They fill refractory castables. They minimize weight while protecting. They are utilized in aerospace elements. They help take care of warm in electronics.

The key advantages are clear. High pureness alumina makes certain chemical inertness. It withstands rust from acids and antacids. The product manages severe heat dependably. It maintains strength over 1500 ° C. The spheres use regular shapes and size. This ensures uniform performance. The hollow bubbles provide premium insulation. They substantially reduce heat transfer. Both products are long lasting and long-lasting. They offer good worth over time. They are important for sophisticated commercial procedures.

Applications of 99% Alumina 0.2- 0.5 mm 0.5-1mm Balls Alumina Bubble Ceramic Hollow

These 99% alumina spheres and hollow bubbles offer vital duties throughout difficult industries. Their high pureness provides outstanding heat resistance and chemical security. This makes them essential where various other materials fail.

The hollow alumina bubbles are principals in high-temperature insulation. They are blended right into refractory castables and plastics. This creates linings for furnaces and kilns. These cellular linings withstand extreme warm far much better than typical alternatives. The entraped air inside the bubbles dramatically decreases warm transfer. This conserves substantial energy. Shops also use these bubbles in financial investment casting molds. The bubbles provide exceptional insulation throughout metal putting. They guarantee smoother steel flow and far better casting results.

The tiny solid alumina rounds (0.2-0.5 mm and 0.5-1mm) are precision grinding media. They are excellent for grinding fine powders in markets such as electronic devices and pigments. Their firmness and wear resistance keep item contamination exceptionally reduced. They keep consistent bit size over extended periods. This dependability is vital for quality assurance.

These alumina rounds additionally function as superb filler products. They reinforce compounds requiring thermal security and electrical insulation. Plastics and resins gain from their addition. The balls increase mechanical stamina and warm deflection temperature level. This is essential for parts near engines or electronics. The rounds’ constant dimension makes sure even circulation within the material. This uniformity assurances predictable efficiency.

Chemical handling devices depends on these alumina porcelains also. Their resistance to corrosive acids and bases is impressive. They are loaded right into columns and reactors as inert assistance media. Drivers commonly sit on beds of these rounds. The balls give secure, unreactive surface areas. Their smooth shape permits optimal fluid flow via systems. This protects against clogging and pressure decreases.

5 FAQs of 99% Alumina 0.2- 0.5 mm 0.5-1mm Balls Alumina Bubble Ceramic Hollow

Here are the top 5 questions people ask about our 99% Alumina Hollow Balls (0.2-0.5mm and 0.5-1mm sizes):

What exactly are these alumina hollow balls?
These are tiny ceramic spheres. They are made from very pure alumina (99% Al2O3). The key feature is the hollow center. Think of them like microscopic bubbles. This structure gives them unique properties.

Why use hollow balls instead of solid ones?
The hollow design makes them incredibly light. This low density is crucial. They trap air inside the bubbles. Trapped air is a great insulator. So, these balls provide excellent heat insulation. Solid alumina balls don’t do this as well. They are much heavier too.

Where are these alumina bubbles typically used?
Their main job is high-temperature insulation. You find them lining industrial furnaces and kilns. They work well in places needing lightweight, heat-resistant materials. They are also used in special refractory castables. They help reduce the weight of the final product.

How much heat can they handle?
These balls are built tough. They withstand extremely high temperatures. They work reliably up to 1700°C (about 3090°F). This makes them perfect for demanding thermal applications. They keep their shape and insulating power under intense heat.

What size options do you offer?
We supply two main size ranges. You can get the smaller balls between 0.2 millimeters and 0.5 millimeters. The larger size is between 0.5 millimeters and 1.0 millimeters. These sizes cover common industrial needs.
