Exploring Ceramics Mould Techniques

What is the primary purpose of powder metallurgy in ceramics?

• To create large ceramic sculptures

• To produce high-density ceramic components

• To enhance the colour of ceramics

• To reduce the weight of ceramic products

Which of the following is a key advantage of ceramic injection moulding?

• It requires no heat

• It allows for complex shapes with high precision

• It is the cheapest method for all ceramic products

• It uses only natural materials

During the sintering process, what happens to the ceramic particles?

• They dissolve in water

• They are cooled rapidly

• They bond together at high temperatures

• They are painted

What is the main benefit of isostatic pressing in ceramic processing?

• It uses less energy than other methods

• It applies uniform pressure from all directions

• It is faster than other pressing methods

• It requires no moulds

In powder metallurgy, what is the typical size range of the ceramic powder particles?

• 1-10 feet

• 1-100 micrometres

• 1-10 miles

• 1-100 ounces

Which material is commonly used as a binder in ceramic injection moulding?

• Water

• Plastic polymers

• Metal alloys

• Sand

What is the typical temperature range for sintering ceramics?

• 100-200°C

• 600-1000°C

• 1500-2000°C

• 3000-4000°C

Isostatic pressing can be performed at which of the following conditions?

• Only at room temperature

• Only at high temperatures

• At both room and high temperatures

• Only in a vacuum

What is the main disadvantage of ceramic injection moulding?

• Limited to simple shapes

• High initial setup cost

• Low production speed

• Poor surface finish

In powder metallurgy, what is the purpose of the compaction step?

• To melt the powder

• To increase the density of the powder

• To cool the powder

• To colour the powder
