Cement plant clinker dust is more abrasive than sand. In high temperature ducts, or ducts with wear potential, 2 + 1 ⁄ 2-inch refractory, is often anchored to the duct plate with V anchors at 6" O.C. (+/-) to resist a) temperature, or b) wear at elbows or a combination of these effects. Occasionally ceramic tiles or ceramic mortars are ...
Ultra-high-temperature ceramics (UHTCs) are a type of refractory ceramics that can withstand extremely high temperatures without degrading, often above 2,000 °C. [1] They also often have high thermal conductivities and are highly resistant to thermal shock, meaning they can withstand sudden and extreme changes in temperature without cracking or breaking.

Cement clinker is a solid material produced in the manufacture of portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter.
