■ ADJECTIVE

In nephrite it occurs exclusively as ferrous and in jadeite as ferric oxide .

Ferrite, the low-cost non-cobalt material made of ferric oxide and barium or strontium carbonate, was launched in the 1950s.

iron

The addition of iron oxide produced a darker brown colour in the glaze under reducing conditions.

nitric

nitrous

■ NOUN

calcium

Some glazes contain elevated magnesia which increases their durability; this was certainly necessary given the low calcium oxide levels.

Another very unusual feature of these glasses is that they contain very low calcium oxide levels-c. 1 %.

When calcium carbonate is heated it decomposes into calcium oxide and carbon dioxide.

emission

lead

When low levels of lead oxide are present there can be a problem of dissolving the copper in the glass.

With a few exceptions most of the translucent glasses contain below 1 % lead oxide .

The white glass also contained 12.0010 of lead oxide: this would have made it softer and therefore easier to cut.

The sulphur was burned off, thus producing a lead oxide which then had to be reduced leaving behind the pure lead.

level

Some glazes contain elevated magnesia which increases their durability; this was certainly necessary given the low calcium oxide levels .

They contain between 0.6 % and 0.8 % magnesia and contain low potassium oxide levels .

manganese

Some scientists are concerned about long-term exposure to low levels of manganese oxides from car exhaust fumes.

metal

How can we tell whether carbon or another metal will reduce a metal oxide ?

nitrogen

To avoid further damage to sensitive ecosystems, sulphur and nitrogen oxide emissions must be cut by 90 percent.

First, the nitrogen oxides are toxic to animals.

Both countries would also limit nitrogen oxide emissions through stricter controls on motor vehicles.

Global warming occurs when carbon dioxide and some other gases, such as methane and nitrogen oxides , accumulate in the atmosphere.

Reduction of nitrogen oxides from cars will need more expensive vehicles - or mean less use.

The nitrogen oxides are almost as effective as dust at screening out sunlight.

Nitrogen oxide Forty percent of nitrogen oxide emissions in Britain come from vehicles.

The situation is exacerbated by unusually low levels of nitrogen oxides , which inhibit ozone destruction.

tin

The waste contains tin oxide , in proportions too minute for last century's miners to recover.

Flotation is important in separating particles of tin oxide less than about 40 micrometres in diameter.

The chemicals have to be carefully selected so that they affect only the tin oxide and nothing else.

Into these flowed more molten rock, carrying minerals such as tin oxide .

■ VERB

contain

The gas was to reduce iron oxide to make iron which could later be fed to a steel works.

How can we tell whether carbon or another metal will reduce a metal oxide ?

EXAMPLES FROM CORPUS

At a given temperature, the oxide with the higher line will be the one that is reduced.

Both countries would also limit nitrogen oxide emissions through stricter controls on motor vehicles.

However, the oxide mineral content of the rocks is generally low, at 5-10 percent.

It would also reduce sulphur dioxide and nitrous oxide emissions, which cause acid rain, by 42,000 tonnes.

Moreover, a strong presence of ferrous oxide in the walls gives them a red color.
