メタけい酸/水/マグネシウム

化学的特性Sepiolite is similar to attapulgite but has an additional SiO4 tetrahedron at regular intervals on the chain, so that the united cell is about 50% larger than that of attapulgite; usually clay-like, nodular, and fibrous; also compact massive (meerschaum) or leathery (mountain skin). . Hardness: 2–2.5 on Mohs’ scale . Density:～2 . Color: White with tints of gray-green or red; also light yellow

解説セピオライト，Mg9Si12O30(OH)6(OH2)4・6H2O あるいは Mg8Si12O30(OH)4(OH2)4・8H2O 。海泡石ともいう。緻密土状の単斜晶系または斜方晶系の鉱物。硬度2～2.5，比重2。灰色，白色，不透明。変質鉱物として蛇紋岩に産出する。白，クリーム色のものはパイプに加工。トルコ，ギリシアなどが主産地。語源はギリシア語の sepia (イカ) で，形がイカの甲に似ているためにつけられた。

説明Sepiolite has been proven to be an excellent absorbent material due to its high porosity and absorptive capacity, making it highly suitable for use in cat litter and industrial absorbents. Additionally, sepiolite's natural properties make it an ideal carrier for insecticides and herbicides, ensuring effective distribution and application.In conclusion, the demand for sepiolite is expected to continue growing in various applications, with the highest growth rates projected in industrial and animal feed sectors.

使用A primary use of sepiolite was as an animal waste absorbent (cat litter).

一般的な説明Sepiolite is a hydrated magnesium silicate that belongs to the class of sepiolite-palygorskite. Its properties include high absorption capacity and good rheological behavior.

Aparticularly pure form of sepiolite mined in Europe and the Middle East is known as “meerschaum” and has been used historically for carving pipes and cigarette holders. Sepiolite production in 1983 was less than half of the estimated 1.1 million of attapulgite in the world.
