carbonate

In addition to carbonates and metal hydroxides, these products are also claimed to react with the surface of talc and of cellulosic fillers.

Planetary scientists, reasoning that Mars used to be warmer and wetter, thought it, too, would have thick layers of carbonates .

He thought the temperatures and pressures of the mantle would convert carbonates and water into hydrocarbons.

The most common minerals in seep carbonates are microcrystalline calcite, microcrystalline aragonite and dolomite, and pyrite as well.

However, near the escarpments of the Cumberland Plateau, evidence of solution of carbonates beneath clastic rocks becomes apparent.

The resorcinol carbonates can be synthesized by the reaction of resorcinol with phosgene or diphenyl carbonate.

Both of physical and chemical methods are being used to produce calcium carbonates.

Reservoirs are mainly hosted by syn-tectonic fractures and associated secondary pore systems in carbonates of the Barents facies zone.

Crystalline hydrated holmium and erbium carbonates were synthesized using ammonium bicarbonate as precipitant.

potassium hydroxide for industrial use . determination of carbonates content . gas - volumetric method.

But none have been found. That means any oceans were cold or short- lived or ice - covered or otherwise hostile to carbonates.

Abstract: The Lower Paleozoic carbonates of Tarim Basin were marbleized locally due to the thermal effects of magma intrusions.

Preferred modifiers include cement, lime, slaked lime, soda ash, carbonates, silicates and phosphates.

Effect of different concentration of carbonates and bicarbonates treatment on black spot and blue mold of postharvest Yali pear was studied.

Research is needed on chemical methods to accelerate the natural weathering process by which minerals form carbonates.

Formation of Late Neoproterozoic Cap Carbonates and Termination Mechanism of "Snowball Earth"

What conditions are required to enhance the thermodynamics and kinetics for forming stable iron carbonates?

This paper reports on the full scale tests of production of crystalline rare earth carbonates from low grade heavy rare earth ores.

The formation and distribution of high quality reservoirs are key to the prospecting in deep marine carbonates.

The mixing deposits mean the mixing of terrigenous clastics (siliciclastics) and carbonates (including allochem grains).

As important inorganic industrial chemicals, calcium carbonates have wide uses.

The secret is using magnesium oxides instead of calcium carbonates, the main ingredient in Portland cement, the most common type.

Thus, the reaction with aryl-substituted allylic carbonates is regioselective.

However, other rocks are also radioactive, notably some carbonates and feldspar-rich rocks.

Carbon and Oxygen stable isotopes in carbonates have long been the important geochemical tracers.

Extenders for paints - Specifications and methods of test - Part 11 : natural talc, in lamellar form, containing carbonates.

Acidic water could have destroyed the bulk of the carbonates but surely not all of them!

In this paper the electrochemical oxidation of activated carbon in molten carbonates were studied. DCFCs were assembled and tested.

SODIUM HYDROXYDE FOR INDUSTRIAL USE. DETERMINATION OF CARBONATES CONTENT. GAS VOLUMETRIC METHOD.

Van Houten treated the powder with alkaline salts (potassium or sodium carbonates) so that the powder would mix more easily with water.

Crystalline RE carbonates are simple crystal lo-hydrates of RE carbonates.

In order to ensure the increasing growth of petroleum production and reserves, the exploration for marine carbonates has to be reinforced.

New carbonates will no longer be laid down.

and carbon-containing compounds such as the carbon oxides, metal carbonyls, carbonates and transition metal carbonxylates.

The acidtreated packing causes release of co2 from inorganic carbonates.

Acidic water destroys many kinds of minerals, particularly carbonates, and it also inhibits the formation of other minerals such as clays.
