HA Fractalballs™  Product Specifications

HA Fractalballs™ are made of high purity Alumina.
 

HA FRACTALBALLS™ may be used as thermal insulation, chemical substrates or as structural materials when bonded with FRACTALPASTE™.

Use as thermal insulation: HA FRACTALBALL™ has very low density, low thermal conductivity, high strength, and high melting point; it can be formed into any shape and size and be used in any refractory/insulation parts for high and low temperature application.

Use for high surface reactivity: HA FRACTALBALLS™ have very high porosity/low density, high strength, and high melting point. They may be used for high temperature filter and membrane substrate applications.

Typical Applications are:

• Light weight structure materials.
• Composite manufacture reinforcement additive for metal, ceramic, or polymer.
• Armor, bio-ceramic, abrasive brake pads etc.
• Coatings for surfaces (metals, ceramics, polymers.)
• Thermal insulation
• Fire protection and stops
• High temperature furnace linings
• Kiln furniture
• Gas combustion burners
• Repairing or relining refractory cracks and holes
• Other applications are:
• Filter
• Molten metal castings (aluminum, copper, iron)
• Steam cleaning.
• Apply as light weight coating for vehicles
• Oil trapping and recovery; grease filters; chemical and water purification processes
• Hot-gas filter substrates for electrode.
• Electronic substrate carriers for bio-reactors.
• Desiccants
• Substrates for catalytic converters
• Use as light weight structural materials

HA FRACTALBALL™ is a unique lightweight, non-hollow porous ball with a very low density and high strength. The material of the HA FRACTALBALLS™ (Alumina) has excellent heat, chemical and mechanical stability; the spheres have low thermal conductivity and high thermal shock resistance. The spheres are sold in a fully fired condition with excellent dimensional stability up to 2000°C. FRACTALBALLS™ are environmental-friendly materials: they do not contain any hazardous materials such as organic volatents or fibrous materials, and will not produce any smoke or odor when heated. They also have desirable chemical, physical and mechanical properties, such as inertness to chemical attack (solvents, acids, alkalies, and detergents), non-wettability by molten metals such as aluminum, high thermal stability, high strength, and micro-biological stability. These features permit the FRACTALBALLS™ to be used in various applications.
HA FRACTALBALLS™, which are made from Alumina, may be used in loosely stacked form or bonded into any size and shape part by bonding the FRACTALBALLS™ with FRACTALPASTE™. These flexible processing possibilities allow FRACTALBALLS™ to be use in various technologies.

HA FractalBalls™ have a porosity of about 55%; when loosely stacked the porosity is about 80%,
HA FractalBalls™ glued with FractalPaste™ has a strength of 4MPa whereas HA Fractalins™ have a
strength of about 5MPa.

The composition of HA material is given in the specification. Patents Applied For and Pending.
