Minerals, aggregates, and mineral powders are commonly used to extend, fill, strengthen or modify plastics, coatings, adhesives, and other materials. Many minerals, aggregates and sands are used as fillers and extenders in other compounds because they are chemically inert. Mineral powder such as mica or slate is used in paints, resins, and plastics.
'Mineral aggregates' will be used to designate aggregates of mineral particles only (no oil), and 'clay minerals' will be used when referring to the phyllosilicates (i.e. kaolinites, smectites, illite/mica, and chlorites), as opposed to other minerals such as quartz, feldspars or calcite.

Mineral xide Aggregate (MTA) was originally formulated as a root-end filling material in apical surgery. 68 It is available in either grey or white forms and is, chemically, similar to Portland cement (mixture of dicalcium silicate, tricalcium silicate, tricalcium aluminate, gypsum and tetracalcium aluminoferrite), but made radiopaque due to the addition of bismuth oxide. 69 It is …

As the type of OMA formed is influenced by oil concentration and oil/mineral ratio, the abundance of solid OMA, or even flake OMA, will vary considerably depending on the local conditions and how soon OMA form after the spill. The ratio of oil to mineral is obviously the primary factor controlling OMA buoyancy.

An example of an aggregate, apart from Jasper, is dolomite rock. Dolomite rocks are made out of mineral crystals of dolomite, a carbonate mineral that is made out of calcium magnesium carbonate. Other examples of aggregates are Lapis lazuli, which is an aggregate of a wide variety of minerals like calcite, phlogopite, pyrite, and lazurite.

The minerals formed depend on temperature and the chemical make-up of the lava and gases. Some form in the early hottest stage or as lava becomes solid. Others form from escaping gases and vapours that react with the colder rims to leave minerals behind. Some minerals also grow in cavities left by escaping steam.

Ore. A mineral or aggregate of minerals from which a valuable constituent, especially a metal, can be profitably extracted. A (4-Hydroxyphenyl)glycine. This derivative (23) forms aggregate spheres or shiny leaflets from water. It turns brown at 200°C, begins to melt at 220°C, and melts completely with decomposition at 245 —247°C.
