Alkali resistant refractories are a type of refractory materials specifically designed to withstand the corrosive effects of alkali compounds, such as alkali metal oxides (e.g., sodium oxide and potassium oxide), alkali metal sulfates, and alkali metal chlorides. These refractories are commonly used in industries where alkali-rich environments are present, such as cement, glass, and chemical manufacturing.
Alkali resistant refractories have excellent resistance to alkali compounds, preventing their penetration into the refractory material. This resistance is achieved through careful selection of raw materials and specific formulations.
Alkali resistant refractories have a dense structure that minimizes the porosity and permeability of the material. This helps to prevent alkali compounds from infiltrating into the refractory and causing damage.
