ACC® Microsilica

Select best silicon products from top manufacturers. The recycle, densifying and filling processes are automatically integrated in a closed environment without any mixture or impurities.

Fix clients’ order in a stable production bases so as to ensure the consistency and stability of quality.

Offer anti-uv & anti-aging plastic woven bag for long storage and also directly-used water soluble paper bag.

Own warehouses in both Tianjin and Xiamen, which ensures timely shipment for urgent needs from clients.

Pass through double quality check from both manufacturer side and ACC side after production and before delivery to ensure quality.

For Construction

With high pozzolanic activity index, high compressive strength and low LOI, ACC microsilica can be well-performed in construction application, which can improve the bond strength and abrasion resistance, reduce permeability, and protect reinforcing steel from corrosion. They are classified as various grades. It’s collected, and packed from silicon metal or ferrosilicon factories directly, the automatic and integrated production process guarantees the consistent quality.

For Refractory

Our grades of G94U & G96U can be well used in the refractory application. It can improve the fluidity of refractory casting materials, reduce water consumption, improve the compactness, temperature strength and thermal shock resistance.

For Fertilizer

ACC microsilica can also be well-performed in other special applications, such as fertilizer. With large surface area, strong absorbability, high whiteness and purity, it can be used as moisture absorption, anti-caking agent, and pellet binding agent.etc for fertilizers. 

White Microsilica/Zirconia Silica fume

ACC ZSF Grade is white microsilica with SiO2 up to 92% -96%; as a by-product of zirconia, it has excellent features both in silica and zirconia, such as high SiO2 content, fine granularity, large surface area and good fluidity to enhance the wear resistance, durability and reinforcement performance in the fields of injection materials, cement and concrete, refractory, ceramics and electronic materials.


ACC microsilica is supplied in a range of packagings:

Jumbo bag with PE liner which conforms to GB/T10454 and EN ISO 21898

with uv-proof function and anti-aging character.
