description
Clinoptilolite is a natural zeolite comprising
a microporous arrangement of silica and alumina tetrahedra. It has the complex
formula: (Na,K,Ca)2-3Al3(Al,Si)2Si13O36·12H2O.
Detailed
description
It forms as white to reddish tabular monoclinic tectosilicate crystals with
a Mohs hardness of 3.5 to 4
and a specific gravity of
2.1 to 2.2. It commonly occurs as a devitrification product
of volcanic glass shards
in tuff and as vesicle fillings in basalts, andesites and rhyolites. It was described
in 1969 from an occurrence in Owl Canyon, San Bernardino County, California.

Use of clinoptilolite in industry and academia
focuses on its ion exchange properties
having a strong exchange affinity for ammonium(NH4+). A typical example of
this is in its use as an enzyme-based urea sensor. It is also used as fertiliser and sold as
a deodorizer in the form of
pebble-sized chunks contained in a mesh bag.
Research is generally focussed around the shores of
the Aegean Sea due to the
abundance of natural clinoptilolite in easily accessible surface deposits.
The name is derived from the Greek words klino
(κλίνω; "oblique"), ptylon (φτερών; "feather"), and lithos
(λίθος; "stone").
