Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
Silica refractories are mainly made from raw materials rich in silica \((SiO_2)\). The commonly used raw material for silica bricks is quartzite.
Step 1: Silica refractories contain a high percentage of: \[ SiO_2 \]
Step 2: Quartzite is a dense and hard rock rich in silica.
Step 3: It is suitable for preparing silica bricks because it provides high silica content and good refractory properties.
Step 4: During firing, silica undergoes phase transformations such as quartz to tridymite and cristobalite.
Step 5: Therefore, quartzite is commonly used to prepare silica refractories. Hence, the correct answer is: \[ \boxed{\text{Quartzite}} \]
