Question

Segar cones are used for the determination of

• A. Electrical conductivity
• B. Softening temperature of refractories
• C. Spalling resistance
• D. Resistance to slag attack

Hint:

Segar cones are commonly used in ceramics and refractory industries to determine the softening temperature at which a material will start to deform.

Answer 1

The Correct Option is B

Segar cones are used to measure the softening temperature of refractories, which is a critical property in assessing their performance in high-temperature environments.
