What is the difference between 98% fused magnesia and 97% fused magnesia

The main difference between 98% fused magnesia and 97% fused magnesia lies in their purity. The purity of fused magnesia is usually expressed as a percentage, with 98% fused magnesia indicating a magnesium oxide (MgO) content of 98%, and 97% fused magnesia indicating a magnesium oxide content of 97%.

Generally speaking, higher purity fused magnesia may have better performance in some applications. For example, in high-temperature industries, higher purity fused magnesia may have higher refractory performance and better resistance to chemical erosion. However, specific application requirements will determine which purity of fused magnesia is more suitable. In addition, besides purity, other characteristics of fused magnesia, such as particle size distribution, crystal morphology, density, etc., may also affect its performance. Therefore, when selecting fused magnesia, not only purity but also other factors need to be comprehensively considered to meet the specific application requirements.
