Spherical Alumina
What Is Spherical Alumina?
Spherical Alumina (Al₂O₃) is a highly pure aluminium oxide material that has been treated in an accurate and even sphere shape. Different from the irregular shape of aluminum oxide, the geometrical shape of the material is controlled by the advanced molding and sintering technology, which gives a uniform size distribution.
The special construction of this Spherical Alumina has a distinctive feature. It has the inherent chemistry of aluminium oxide – high hardness, good heat resistance, and good electric isolation – with additional mechanical and fluid advantages that can only be achieved by spherical shapes.
The Spherical Alumina has a wide variety of grain sizes and purity levels, and it has wide applications in all fields that require no negotiation on accuracy, reliability, or exceptional properties. It is used as a key function for modern industrial processes from heat management in electronic equipment to catalytic support in petrochemicals.
Why Choose Spherical Alumina?
-
Superior FlowabilityThe flat, circular surface ensures that the friction between the grains is kept constant and the density of the filler is constant - necessary for automatic filling, painting and mixing.
-
Excellent Thermal Conductivity Spherical Alumina is an efficient heat-dissipation agent, which is the first choice for heat-conducting plastics, epoxies, and electronics encapsulation.
-
High Packing DensityIts homogeneous ball form permits a more compact and effective filling than an angle or an irregular grain, thereby improving the filling speed while not affecting the processing properties of the material.
-
탁월한 기계적 강도The homogeneous configuration of the balls gives an even distribution of the stress to the ball, which offers increased abrasion resistance and long term endurance in an abrasive or high pressure environment.
-
Consistent Particle Size Distribution Tight Dimension Control guarantees the homogeneity of the batch to the lot, minimizing the number of flaws in precise applications like the grinding slurry, the ceramic parts and the electronics.
-
Chemical Stability & Electrical Insulation With a High Pure Al₂O₃, Spherical Alumina provides superior performance against acids, alkalis, and high-temperature conditions, as well as good dielectric performance for insulating purposes.
업계의 과제
높은 생산 비용
Achieving uniform spheroidal shape demands an advanced fabrication technique, which leads to a considerably higher manufacturing cost compared to the normal irregular aluminum oxide powder.
Precise Particle Size Control
Maintaining Compact Grain Size Distribution is still a technical challenge because even small variations can affect the properties of the final product.
Dispersion in Polymer Matrices
Without appropriate surface handling, Spherical Alumina grains are prone to agglomerating in the resin or polymeric system, resulting in a reduction in heat and mechanical properties.
Surface Modification Requirements
Many applications need extra surface functionality in order to increase compliance with the organic matrix, which increases the complexity of the manufacturing process and the cost.

Why Use Our Spherical Alumina
Uniform Spherical Morphology
Precision-controlled spherical geometry guarantees uniform grain size throughout each batch, providing predictable performance for high precision applications like electronics, grinding slurry, and ceramic parts.
High Thermal Conductivity
Spherical Alumina is an ideal packing material for heat-conducting composite materials with superior heat-dissipating properties, which can assist in efficient management of heat build-up and prolong operating life.
High Packing Density & Filler Loading
The ball form allows for effective granular filling and a higher filling speed in the polymeric and resin systems, thereby enhancing the performance of the material while not substantially raising the viscosity or impairing the machining capability.
