Chemical Formula: Al2Si2O5(OH)42H2O+SiO2
Halloysite Description:
A clay like mineral, occurring in soft, smooth, amorphous masses, of a whitish color. Halloysite frequently has a unique tubular quality, not unlike a grain of rice, only considerably smaller and hollow.
Halloysite is 50% silica and 50% clay. Al2Si2O5(OH)42H2O+SiO2

1) Halloysite clay is used to produce the highest quality tableware china manufacture including porcelain, bone china and fine china.
2) The fineness of particle size enables halloysite clays to be used extensively as suspension agents in glaze preparations. The purity of the clay and the low iron and titania content produce exceptional whiteness and translucency to ceramic ware.
3) A small but increasing amount is used for hi-tech ceramic applications. Honeycomb catalyst support units are used in the exhaust systems of motor vehicles to clean up exhaust gases. Molecular sieves (synthetic Zeolites) are used in a wide range of applications including separation of liquids and gaseous mixtures, water purification, and in refining industries.
4) Halloysite microtubules can act as a time release capsule, dissolving over time, and can be filled with such things as antifouling paint, antiscalants, herbicides, pest repellants, and other agents that could benefit from a controlled release.
