1. Main component: one or several refractory oxides or non-oxides with high melting point in refractory materials. It is the main body of refractory products and directly determines the performance of refractory products. The nature and quantity of magnesia brick wholesale heat storage bricks play a decisive role in the performance of refractory materials.
Refractory materials can be divided into three categories according to their main components

The significance of dividing refractory materials according to their main components is to understand the chemical properties of refractory materials and judge whether there is a chemical effect between them and between refractory materials and contact objects during use.
2. Additives
The amount added is very small, or even very small; it is used to make up for the shortcomings of the main component in certain aspects such as use performance, production performance or operational performance, which can significantly improve a certain function or characteristic of the refractory product, and the main performance of the product is not Serious impact. Usually there are binders, mineralizers, stabilizers, sintering agents, water reducing agents, anti-hydrating agents, antioxidants, coagulants and expansion agents. . Refractory materials are generally heterogeneous bodies composed of a variety of different chemical compositions and minerals. Its various properties not only depend on its chemical composition, but also depend on the phase composition, distribution and characteristics of each phase, that is, it depends on the chemical and mineral composition of the product. According to the chemical composition of refractory materials, the components are divided into main components, impurity components and additives.
