alumina

It is the site of the first alumina factory in Africa.

The Russians are believed to buy at least half their alumina from foreign suppliers.

Alumina is unstable in the pH range from 7 to 11.

Where do they get their partly refined alumina from?

Bauxite, alumina, and aluminum make up most of the exports.

Alumina nanofibers in particular have become a research field of interest.

Probably this vessel would need to be an alumina or porcelain crucible.

Some alumina is available with rather large pore-sizes about 10 Angstroms.

In 2005, Guinea was the only African producer of alumina.

It also differs according to the amount of alumina present in it.

However, the company's main strategy focuses on mining and alumina refining.

It has in combination a minute portion of alumina and silica.

The two overlap in producing alumina, a compound from which aluminum is produced.

The container is sealed at the top with an airtight alumina lid.

For example, additives that form the alumina as a powder rather than a gel have been developed.

It has about 25% of the global alumina market.

A dehydrogenating catalyst, such as platinum on alumina, is required.

For molten metals, alumina is used only with gold and platinum.

It is also a raw material for activated alumina.

Ion exchange and activated alumina have been considered but not commonly used.

It is based on the extraction of alumina with sodium carbonate.

It is a silicate of alumina and soda with some chlorine.

In older patients this effect can cause bone loss and loosening of alumina based implants.

The stationary phase is a solid adsorbent such as alumina.

For these reasons, an alumina substrate is commonly used.
