A byproduct from the New Zealand Dairy Corporation (NZDC) factory at Te Awamutu, fluidised bed boiler ash (FBA), contains agronomically useful amounts of lime and sulphur (S). The FBA is produced from injection of limestone into the combustion chamber to absorb and reduce sulphur dioxide (...

In contrast, the lime alone treatment had little effect on subsurface soil properties. Use of dolomitic limestone to supply magnesium (Mg) in conjunction with the CaSO4 treatments was more effective than supplementation with Mg(OH)2, where97% of the added Mg leached from the top layer. ...
Upward migration of contaminants was evaluated over a 20-month period. Soluble salts migrated upward 15 to 30 cm into the overlying soil, and salt movement appeared to be governed to a greater extent by diffusive rather than convective flow mechanisms. Capillary barriers of coarse limestone ...
On a yet finer scale, certain classes of solids containing 'giant molecules' have their chemical properties determined by the shape of those molecules, whether forming thin sheets, fibres, or a loose network. Examples are graphite and other forms of carbon, textile fibres and the zeolites. The...

and many of them while look different, or were formed in different natural processes, they are very similar in composition (for example limestone, calcite, aragonite). Some naturally occurring substances are even chemically identical, however they have very different properties and structures (su...
Chemistry is concerned with the composition and properties of matter, and with the transformations of matter that can occur spontaneously or under the action of heat, radiation or other sources of energy. From the results of chemical experiments the chemist singles out a particular class of ...
