ceramic process(2)

LET'S HAVE FUN!!!

Spin thewheel!

FOR 25 POINTS

What is two stages of crystallisation of a glass to produce glass-ceramics?

25 POINTS

nucleation and crystal growth

absorption and adsorption

oxidation and reduction

Keep spinning the wheel!

25 POINTS

BRAV0!!!

FOR 100 POINTS

Why is heterogenous nucleation occurs faster?

100 POINTS

Because the free energy barrier is high

Because the free energy barrier is in equalibrium

Because the free energy barrier is low

Keep spinning the wheel!

100 POINTS

MANTAPP!

FOR 75 POINTS

Nucleation rate decrease after it reach a maximum. True or false?

75 POINTS

False

True

Keep spinning the wheel!

75 POINTS

PADU LAHH!

FOR 250 POINTS

What is the name of the process when involving the crystallization from a glass powder compact?

250 POINTS

Volume Crystallization

Sinter Crystallization

Keep spinning the wheel!

250 POINTS

PERFORM!!!

FOR 50 POINTS

Why controlled crystallization are required in volume crystallization?

50 POINTS

To produce a uniform material, free of defects (cracks, holes and surface roughness).

To prevent a uniform material, free of defects (cracks, holes and surface roughness).

Keep spinning the wheel!

50 POINTS

MANTOLL!!!

FOR 500 POINTS

Tiles is one of an example of a manufacture product that can be produced from sinter-crystallization process?

500 POINTS

True

False

Keep spinning the wheel!

500 POINTS

HEBAT LAH AWAK NI

FOR 500 POINTS

What are the processes including in glass?

500 POINTS

melting & solidification processing

cooling and heating process

particulate processing

Keep spinning the wheel!

500 POINTS

HEBAT LAH AWAK NI

FOR 250 POINTS

What is the raw material in glass?

250 POINTS

Silicon carbide

Aluminosilicates

Fluxes

Keep spinning the wheel!

250 POINTS

WOWERRZZZ!!

FOR 50 POINTS

Which is the second step of glass making?

50 POINTS

Molten glass is fed as 'gobs' to an automatic bottle or jar making machine.

The bottles or jars pass into a lehr (an annealing oven), where they are first reheated to soften the glass to remove stresses, and then cooled gradually to prevent stresses developing.

Keep spinning the wheel!

50 POINTS

WOWERRZZZ!!

FOR 250 POINTS

Bottles, jars, plates and light bulbs undergo discrete process for shaping.

250 POINTS

False

True

Keep spinning the wheel!

250 POINTS

EXCELLENT!!

FOR 500 POINTS

What is the shaping process of wide-mouth containers production?

500 POINTS

Press-and-blow

Spinning

Casting

Keep spinning the wheel!

500 POINTS

GOOD JOB!!

FOR 500 POINTS

In blow-and-blow shaping process, the air is blown into the hot parison to expand the glass tightly against the mould walls.

500 POINTS

True

False

Keep spinning the wheel!

500 POINTS

FANTASTIC!!

TRY AGAIN!
