三河珪石 Company Profile

Creating the future together with our customers through sand! Leave Mikawa silica to us.

Our company is one of the few manufacturers of artificial silica sand in Japan, effectively utilizing our abundant reserves to broadly support the country's core industries. In the past, silica sand was primarily used for casting due to its high-quality characteristics, but now it is used in a wide range of applications, including construction materials, pesticide carriers, artificial turf infill, and biomass power generation furnaces. We will continue to aim for long-term stable supply to our users and actively promote mining development and the renewal of manufacturing facilities.
