MINERALS AROUND US
Every segment of society uses minerals and mineral resources every day. The roads we drive, and the buildings we live, learn and work in, all contain minerals.
Think about the properties
of tungsten:
– strong;
– very high melting point;
– rigid;
– impermeable.
PEN AND PAPER
Also the writing tips of pens are made with strong metal called tungsten.
Paper is usually made of wood pulp mixed with minerals like clay, mica, talc and baryte.
thixotropic ink in a hermetically sealed and pressurized reservoir
writes three times longer – тиксотропные чернила в герметичном резервуаре под давлением пишут в три раза дольше;
stainless steel, precision-machined socket prevents leaks and oozing,
yet delivers instant uniform ink flow – обработанный на станке с высокой точностью разъем из нержавеющей стали, предотвра-щающий утечки и просачивания, еще обеспечивает мгновен-ный равномерный поток чернил.
Rutile and ilmenite are the main sources of titanium metal, which is used to make a white pigment in paints.
gasket – прокладка;
PTC – полимерный герметик;
vent – отвод;
cathode tab – отрицательный контакт;
anode – анод;
separator – разделитель;
cathode – катод;
anode tab – положительный контакт;
bottom insulator – нижняя изоляция;
steel can (negative terminal) – покрытый сталью (отрицательный вывод);
top insulator – верхняя изоляция;
top cap (positive terminal) – верхняя крышка (положительный вывод).
Let’s look at the picture of cylindrical lithium-ion battery structure
Here is what a laptop is made of
(also refers to a desktop computer):
polyvinyl chloride – поливинилхлорид;
lead – свинец;
antimony – сурьма;
chromium, cadmium and lithium –
хром, кадмий, литий;
beryllium – бериллий;
phosphor – фосфор;
liquid crystal display – жидкокристаллический
дисплей.
FLOWER POTS
We can use another mineral to pot your favourite plant.
Vermiculite is a mineral which expands when it is heated.
It is used as an ingredient in potting mixes to improve drainage.
CEMENT
Clay minerals also make up much of the material used to connect them together – portland cement – a cement that hardens under water and is made by heating a slurry of clay and crushed chalk or limestone in a kiln.
PLASTERBOARD
When powdered gypsum is heated and then mixed with water, it can transform into a solid mass. This makes it a very useful building material, producing the plaster and plasterboard that form the walls around you.
WINDOWS
Glass is made from quartz. It is melted down, and mixed with other ingredients to produce glass of many different sizes, shapes and colours.
Think about the properties of copper:
– flexible;
– stretchy;
– a good electrical conductor.
