Welcome to know the introduction of magnesia-calcium bricks
Posted by annesheldon on January 23rd, 2017
The magnesia-calcium brick, also known as high calcium magnesite brick, is a kind of magnesial refractory material with periclase as principal crystalline phase and tricalcium silicate as secondary phase.It contains 80 % ~ 87% MgO, 6 % ~ 9% CaO, CaO/SiO2 ratio is between 2.2 ~ 3.0.Its significant structural feature is periclase directly contact with dicalcium silicate and tricalcium silicate,making eutectic solution-4 Cao Al2O3 Fe2O3 fill into crystal gap between dicalcium silicate and tricalcium silicate. Its porosity is low, the refractoriness under load is higher than 1700 ℃. It has good alkaline slag resistance ability, but with poor thermal shock resistance.There have many kinds of refractory products in our factory. Such as furnace drying tamp mass, fire brick, refractory nozzle, raw material. When you need any refractory products, welcome to view our website anytime.
