This paper described the influence which the mole ratio of MgO/MgCl2 and an additive which is silicon powder effect on the strength of the magnesia's abrasive products.
论述通过正交试验法对MgO和氯化镁摩尔比以及硅粉对菱苦土磨具强度的影响规律。
First prepare potassium nitrate with nitric acid and potassium chloride reacting with magnesia, and then separate potassium nitrate from solution and mother liquor is mainly composed by magnesium chloride.
先以硝酸、氯化钾与菱苦土为原料反应制取硝酸钾,分离硝酸钾所得母液主要是氯化镁溶液,在氯化镁溶液中先后加入填充料、改性剂、菱苦土等原料,充分搅拌均匀制成菱镁水泥料浆,然后将料浆注入模具中成型为菱镁水泥制品。
The result shows that the cause of fracturing is under-burning or over-burning of magnesia.
指出欠烧或过烧菱苦土的采用是造成氯氧镁水泥硬化体胀裂的根本原因。

Research on the composite magnesia cement of the caustic dolomite and the calcined magnesite;
苛性白云石与菱苦土复合的胶凝材料
Comparisons of machanical properties (experiments) indicated that the strength of magnesium oxychloride cements prepared of caustic (dolomites) and calcined magnesites was very close and the early (strength) of the former was even higher.
通过力学性能对比试验,表明苛性白云石、菱苦土制备的氯氧镁水泥,二者在强度上相差无几,且前者早期强度更高;若二者按一定比例混合制备复合氯氧镁水泥,由于活性MgO含量的增加和弥散分布的活性CaCO3粒子的增强作用,物理力学性能得到很大改善。
In this paper, the functional mechanism of quartz in magnesia bonded abrasives is studied by applying the relevant theory of material structure and chemical bond, and identified the theoretical result by experiment.
