Chemical Characteristics— Vermiculite is a neutral clay, with a pH of 7.0–7.5 and low EC. This clay type contains two tetrahedral sheets for every octahedral sheet. Like the raw material, it has a permanent negative charge. Consequently, it has a CEC value of 15–21 cmol/kg and a buffering capacity for pH and cations.
The Difference Between Perlite and Vermiculite Is Moisture Retention. The key difference between the two mediums is in how each one retains water, as well as how much water each one can retain. This makes them suitable for different applications. Technically, neither perlite nor vermiculite is superior to the other, but each one is better than ...

Vermiculite is a mineral ore that can include asbestos as a harmful waste. It was first found in the year 1824 in the English county of Worchester, Massachusetts but was not commercially mined until the year 1923. After the processes of mining and milling, the ore is then later heated to exfoliate and to be formed into a substance that is fire ...
The extraction of vermiculite generates coproducts that are deposited around mining industries resulting in environmental issues. The aim of this study was to evaluate the use of the equitable combination of fine and ultrafine dust obtained from the.
For potting mixes, a common ratio is one-third vermiculite, one-third coconut coir, and one-third compost. This blend ensures moisture retention and nutrient availability. For garden beds, mix vermiculite into the top 6-12 inches of soil at a rate of 2-3 inches of vermiculite per foot of soil to enhance aeration and water retention.

Vermiculite is found in fine, rare, and somewhat larger sheets, and in other clay minerals with particles <4 μm. It is formed by weathering or hydrothermal alteration of biotite or phlogopite. Vermiculite is an essential ingredient of soil and clay sediments. The mineral can be transformed, easily and quickly, into smectite in surface weathering.
