Precipitated Silica

21 grades

High-purity amorphous SiO₂ with high surface area and controlled particle size — the leading reinforcing filler for green tires, industrial rubber, battery separators, and agrochemicals.

Highly dispersible · Standard · Battery-grade

Silica Sol

20-50 wt% SiO₂

Colloidal SiO₂ nanoparticle dispersion (4-100 nm) — binder for precision investment casting, refractory coatings, photovoltaic wafer polishing, and catalyst supports.

Alkaline · Acidic · NH₃-stabilized

Colloidal Silica

10-80 nm

Discrete spherical SiO₂ nanoparticles in stable suspension — semiconductor CMP slurries, anti-slip floor coatings, zeolite synthesis. Highest particle uniformity (CV<15%).

CMP · 抛光液 · 沸石

Silica Powder

Crystalline · Fused · Spherical

Crystalline, fused, and spherical SiO₂ filler for epoxy molding compounds (EMC), semiconductor advanced packaging, electronic underfill, and high-frequency PCB substrates.

≥99.9% SiO₂ · α-rays ≤1 ppb

Silicon Carbide

4 grades

Synthetic non-oxide ceramic from Acheson carbothermal reduction — Mohs 9.2 hardness, service to 1450°C. Four grade families cover abrasive/refractory bulk, precision ceramic micropowder, and sintered structural ceramic.

Black · Green · Micropowder · Sintered

Alumina (Aluminum Oxide)

4 grades

Workhorse oxide ceramic from Bayer-process aluminum hydroxide calcination — global supply 140 million t/yr. Four grade families: metallurgical (smelter feedstock), calcined (technical ceramic), activated (adsorbent), and high-purity HPA (LED sapphire / battery separator / IGBT substrate).
