Q1:

Ceramic tips for the cutting tool are prepared from __________ powder.

A carbon

B silicon carbide

C aluminium oxide

D tungsten

ANS:C - aluminium oxide

Ceramic tips for cutting tools are commonly prepared from aluminium oxide powder. Aluminium oxide, also known as alumina, is a widely used ceramic material known for its hardness, wear resistance, and thermal stability. It is an excellent choice for cutting tool applications due to its ability to withstand high temperatures and resist abrasion during cutting operations. Ceramic cutting tools made from aluminium oxide are often used in machining applications where high-speed cutting and prolonged tool life are required, such as in the aerospace, automotive, and manufacturing industries.
