Top page Home Company Profile Outline Business content Work Product introduction Products What is diatomaceous earth? About diatomite Contact Contact Sakamoto Suisho has been producing diatomaceous earth since its establishment in 1945. Diatomaceous earth is a rock composed of fossil diatoms formed by depositing the remains of phytoplankton over many years. It is used as a building material and heat insulating material because it has excellent fire resistance and heat insulating properties, as an insulator because it does not conduct electricity, and as an abrasive because of its moderate hardness. Since ancient times, it has been used for wall soil by taking advantage of its high heat retention and moderate hygroscopicity. In recent years, as interest in natural materials has increased, the use of wall soil has been reviewed and is in the limelight. At Sakamoto Suisho, we are engaged in the production of diatomaceous earth and other businesses with the harmony between nature and human life in mind.
