18 May 2006 A wide range of High tech applications : thanks to its physical and chemical characteristics, the RSA dense Alumina Microbeads are becoming a successful solid and technical additive.
Main advantages :
- resistance to corrosion and chemical agents
- higher abrasion and scratch resistance
- resistance to fissuring and cracking
- uniform surface improvement
- no alteration of initial colouring
With a perfect spherical shape, these fused alumina particles have a high density and an excellent flow ability, which adds to well known properties of alumina : high hardness, good electrical insulation and permittivity, chemical inertia.
All these characteristics have been tested successfully in : ceramics, composites materials, specific refractory materials composition, thermocouples insulation
RSA Optronics Microbeads
success of crystal growth
Besides Verneuil crackles widely used as raw material for crystal growth, RSA proposes its High pure Optronics Microbeads alternative for static and continuous feeding systems for crucible charge in bulk crystal growth.
The chemical quality of the product is perfectly controlled, making it easier to directly fill the the crucibles used by all sapphire or laser crystal growing technologies : EFG, Kyropulos, Bagdasarov, CZ for YAG crystals. |
