The Correct Option is C
Solution and Explanation
Concept:
Silica bricks are made from silica-rich raw materials like quartzite. A small amount of bonding agent is required to bind the particles and assist brick formation.
Step 1: Silica bricks are mainly made from: \[ SiO_2 \]
Step 2: During manufacturing, quartzite particles need a suitable bonding material.
Step 3: Hydrated lime is commonly used as a bonding agent in silica brick making. \[ Ca(OH)_2 = \text{Hydrated lime} \]
Step 4: It helps in bonding and also assists in transformation of silica phases during firing. Therefore, the bonding agent used in making silica bricks is: \[ \boxed{\text{Hydrated lime}} \]
