Rare Earth Organic and Inorganic Chemicals from Reliable Sources

Special rare earth elements exist in the periodic table and their utilization is gradually increasing due to their special properties. They are referred to as rare not due to lacking in abundance but rather due to sparse geographical occurrence in the earth crust.

Manufacturing Process of Carbide Chemicals

Carbides are formulated as powders. The processes involved include milling, vacuum drying and spray drying. In attrition milling, carbide balls are fed to the milling machine with a special milling liquid. Other materials are destroyed in the process to achieve a homogenous mix. They are dried in vacuum to prevent oxidation to get the required carbide powder.

Evaporation Materials Applications

Evaporation materials available from green earth chemicals include fluoride evaporation, metal evaporation, mixture evaporation materials and oxide evaporation materials. These materials are used in thermal coating of materials in a method called “thin film deposition” in which the evaporation material is heated in a vacuum chamber, evaporates and the moisture deposits on the material to be coated. The process is used in making of items such as metal coated plastics.

Ferroalloys/Electrode Powder Series

Ferroalloys/Electrode Powder Series include Alv alloy, CaSi alloy. They are used in manufacturing of electrode powder as well as various types of steel alloys.


Film Substrate from Green Earth Chemicals

The film substrate material available from green earth metals includes LaALO3, LaSrAlO4, magnesium oxide, and NdGaO3. These products are used in application of a thin film largely for protection of corrosive material from degradation. A thin film layer of a thickness of 50 nanometers is applied especially in electronic semiconductors and optical devices.

Nitride Chemicals

These are chemicals formed when nitrogen is combined with another element that has the same or even lower electro negativity like that of silicon, or boron and mostly metals. They are classified as ionic, covalent or interstitial. Some nitrides are highly refractory and resistant to chemical attack and therefore used in the manufacture of abrasives and heat resistant products like crucibles. Some nitride chemicals include vanadium nitrogen alloys, aluminum nitrides, Boron and chromium. These are very hard and resistant to any form of chemical attack.

Rare Earth Organic and Inorganic Chemicals

Rare Earth Chemicals

From green earth chemicals, high quality rare earth chemicals include cerium carbonates, cerium fluorides, dysprosium oxides, lanthanum compounds such as lanthanum carbonate, and Neodymium oxide. They have very high refractive index and are incorporated in manufacture of battery electrodes, camera lenses and as part of catalyst in oil refinery.

Scattered Metal

Scattered Metal includes cadmium, gallium, germanium oxide, indium, selenium and tellurium. Selenium shows high photo voltaic activity therefore used in manufacture of solar cells as well as photo conductive action and is very useful in the manufacture of electronic rectifiers.

Silicide Chemicals

These include calcium Silicide, chromium Silicide and zirconium disilicide. The calcium Silicide is useful in the making of special alloys and assisting in the removal of phosphorus as a deoxidizer.

Special Powder/Alloy Series

Special Powder/Alloy Series are metal alloys used in a wide range of industrial functions. The chromium metal powder is highly corrosion resistant thus very effective protective clothing. Tungsten has very high heat resistance and highest melting point of all metals and thus very effective in high temperature applications. Titanium dioxide is very efficient in light scattering and a good whitener when incorporated during plastic making. This whitening effect enhances durability of polymer products.
