Magnesium olivine, which does not contain free SiO2, is a globally recognized environmentally friendly and hygienic material. The departments of product production, application, waste discharge, and regeneration can fundamentally eliminate the occupational disease of silicosis. Hubei Jinmagnesium Mining Co., Ltd. is taking advantage of this resource advantage and has independently developed a series of magnesia olivine refractory materials and biochemical ceramic materials with high temperature resistance, corrosion resistance, and good chemical stability through its unremitting efforts.
Magnesite olivine [(Mg) 2SiO4] (abbreviated as M2S) is used as the main component of refractory material for magnesia olivine refractory material. The content of M2S in the material is greater than 95%, and its M/S ratio is ≥ 1.2.
In addition to the main crystalline phase M2S, there are also a considerable amount of periclase, magnesium ferrite, and other minerals in magnesia olivine refractory materials. The crystalline particles of M2S are large and form a structural skeleton. Other minerals do not exist in the form of complexes, but in the form of inclusions within the cracks of forsterite crystals. Therefore, the properties of magnesia olivine refractory materials mainly depend on the molecular structure of magnesia olivine.
Pure magnesium olivine has a melting point of 1890 ℃ and is a stable refractory phase in the MgO-SiO2 system. M2S does not undergo homogeneous or heterogeneous transformation from room temperature to the melting point range.
Magnesium olivine has a high load softening temperature, and pure magnesium olivine crystal materials and products can start to deform at a temperature of 1650-1770 ℃, or even higher. Its thermal shock stability and water absorption self powder resistance are better than ordinary magnesia bricks.
