Calcium Carbonate

Limestone is a resources that has been nurtured by the Earth since prehistoric times.
This stone, in the course of times, has been playing important roles as materials for construction of civilization and for artistic works.
From 2500 B.C. to 1500 B.C., those beauties of the legacy such as pyramids and the Venus de Milo from ancient Greece were created, making maximum use of the grace, workability, durability, uniformity, and other characteristics brought by limestone.
In present times, limestone is applied in various fields for the use in strong linkage with our lives.

[Measuring Method]
Average Particle Size Powder specific surface area measuring device SS-100 (manufactured by Shimadzu Corporation) was used to measure the specific surface area of 1g of powder. The average particle diameter of the powder was calculated with the following equation.

Average particle diameter = 6/(Specific gravity x Specific surface area) x 10000 [μm]

Residue on 45μm As defined in JIS K5101; 1000g or 2000g of sample was sifted with water on a sifter with openings of 45μm; residue on the sifter
Moisture Content As defined in JIS K5101; Sample was dried at 105 °C for 2 hours to reduce weight.
Apparent Specific Gravity A As defined in JIS K5101 (The status in which powder is placed as softly as possible.)
Apparent Specific Gravity B 5g of sample was collected in a graduated test tube. The test tube was made to fall from the height of 5cm 100 times before the specific gravity was measured.
DOP Absorption As defined in JIS K5101 with necessary modification (DOP was used.)
Whiteness The relative value on a white meter with the whiteness of magnesium oxide (MgO) taken as 100%
In addition to the products listed in this table, we have a wide variety of products. As our products are made of natural minerals, the results of measurement may vary in some extent depending on the origin of mining.
