In calcium carbonate particles, purity and whiteness
are even more critical than particle fineness and uniformity. Creating
a high-quality calcium carbonate product requires "clean" manufacturing
processes and precise control technologies at every stage of production,
from ore handling to final processing. And for calcium carbonate used
in pharmaceuticals and food additives, extremely rigorous quality control
is also a must.
At Bihoku, we boast in-house developed proprietary calcium carbonate technology
that achieves purity of 98.5% or higher. Highly regarded throughout the industry,
this technology lets us supply the high-purity products demanded in cutting-edge
high-tech fields and the new and compound materials fields.

| Small particle size is an essential condition for high-quality
calcium carbonate. Fine particles are created through a grinding process
that uses advanced, specialized equipment and technologies. Bihoku,
drawing on deep experience and a storehouse of sophisticated grinding
technologies, has developed production technology that delivers a reliable
supply of particles smaller than a single micron in diameter. We have
also succeeded in reducing production costs. |

Particle size uniformity joins fineness, purity and whiteness
as key factors in calcium carbonate quality. To assure outstanding
uniformity, Bihoku rigorously tests all products using our own in-house
developed size-classification technologies. In our SOFTON-based calcium
carbonate products, some 90% of the particles measure 2 microns or
less in diameter. These top-quality products have earned high praise
in the industry and see wide use in fields such as paper production,
paints, and construction materials.
