Thermal & Composite Fillers
Thermally conductive ceramic and composite filler powders. Select around the host matrix, loading, processing and final-part evaluation.
Choose a material
Spherical oxide fillers
Choose alumina or silica, then the particle distribution and surface treatment needed by the resin and mixing process.
Spherical silica powder
spherical silica (SiO2) thermally conductive filler powder
SiO2
Boron nitride fillers
Separate agglomerated and platelet BN requirements. Describe the mixing and forming process when comparing particle shape and surface treatment.
Agglomerated boron nitride powder
agglomerated boron nitride powder (BN) thermal-interface filler
BN
Platelet boron nitride powder
Platelet boron nitride (BN) thermal-interface filler powder
BN
Treated and coated fillers
Identify the core and treatment or coating. Compare compatibility in the intended resin; a powder result does not establish the performance of the final composite.
Surface-treated aluminum nitride powder
Surface-treated aluminum nitride (AlN) thermal-interface filler powder
AlN core + surface treatment
Alumina-coated filler powder
alumina-coated composite filler powder (core and coating grade-specific)
Al2O3 coating + specified core

Material selection guide
Start with the material identity and process, then check the details on the proposed datasheet.
Material & surface
Compare BN, AlN and other filler systems by chemistry, morphology and treatment. A coating or surface treatment needs its own description.
Packing & rheology
Specify the particle-size blend, shape and target loading. Flow, dispersion and final-part properties must be considered together.
Evaluation basis
Distinguish powder properties from composite properties. Request the test method, matrix, loading and specimen conditions behind performance data.
Before you choose
Does powder thermal conductivity predict a finished composite?
It does not establish the final formulation result. Interface quality, packing, dispersion, loading and processing all need to be considered in a representative sample.
What does this directory cover?
Raw nitrides remain in the nitride directory; this page focuses on filler morphology, treatment and formulation requirements.
What to include in your request
A material name or reference datasheet is enough to start. Add any requirements you already know.
- Filler chemistry and surface treatment
- Particle distribution, shape and size blend
- Host matrix, loading and mixing/curing route
- Composite test method and target conditions
Quantity, samples and documents
Nike has no fixed minimum order. Tell us the quantity you need; we’ll check supplier pack sizes and any minimums.
We’ll check the proposed grade, sample options, delivery timing and available batch documents. Include any essential COA, TDS or SDS requirements.
