Fused Silica
Fused Silica Powder 325 Mesh
High-purity 325 mesh fused silica powder for refractory, technical ceramics, epoxy molding compounds, electrical insulation, powder coatings, resins, foundry and precision-casting applications.
Fused Silica
Fused Silica Granules 1–3 mm
Review 1–3 mm fused silica granules for refractory, ceramic and foundry trials. Confirm grading, lot chemistry and application requirements before sampling.
Fused Silica
Fused Quartz Sand for Electrical Insulation & Refractories
High-purity fused quartz sand for electrical insulation compounds and refractory formulations. Amorphous silica with low thermal expansion, controlled granular grades and multiple particle-size options for application-specific evaluation.
Fused Silica
Fused Silica Powder for Refractory Castables
Evaluate fused silica powder for refractory castables. Confirm particle size, lot documents, binder compatibility and thermal-cycle requirements before sampling.
Fused Silica
Fused Silica Powder for Electrical Epoxy Casting
Fused silica powder for electrical epoxy casting and vacuum-cast insulation component trials. Grade selection should be matched to the resin, target particle-size distribution, filler loading, mold-filling process, cure schedule and the buyer's finished-component tests.
Fused Silica
Fused Silica Powder for EV Power Module Potting Compounds
Fused silica powder for EV inverter and power-module epoxy potting trials where low expansion and dimensional stability are required. Match purity and PSD to viscosity, vacuum filling, thermal cycling, dielectric strength and partial-discharge acceptance in the customer’s resin system.
Fused Silica
Low-Expansion Fused Silica Powder for Semiconductor Epoxy Molding Compounds
Low-expansion fused silica powder for semiconductor epoxy molding compound screening in advanced packaging. Reference chemistry includes SiO2 >99.90% and Fe2O3 <50 ppm; select PSD and purity against filler loading, flow, warpage, ionic contamination and package-reliability targets.
Fused Silica
Fused Silica Powder for Refractory Gunning Mixes
Fused silica powder for refractory gunning mix trials where phase identity, particle-size control and process compatibility must be evaluated together. Confirm grade-specific chemistry, PSD, moisture and application fit against the customer’s mix and spraying conditions.
Fused Silica
Amorphous Fused Quartz Flour for Ceramic Additive Manufacturing Trials
Amorphous fused quartz flour for ceramic additive-manufacturing feedstock trials, including binder-based printing routes that require controlled powder data and a defined debinding and firing program. Printability and final properties remain formulation- and process-specific.
