尖晶石簡(jiǎn)介：
尖晶石是自然界中少有的一種礦物質(zhì)，必須靠人工合成才能制的。工業(yè)上應(yīng)用的鋁鎂尖晶石全部都是人工合成的。合成鋁鎂尖晶石的兩個(gè)主要方法是燒結(jié)法和電熔法。多數(shù)尖晶石材料是由高純合成氧化鋁和化學(xué)級(jí)氧化鎂制成，即在豎窯燒結(jié)和在電弧爐內(nèi)電熔。鋁鎂尖晶石屬于一種鋁鎂氧化物，其主要成分為氧化鋁和氧化鎂。鋁鎂尖晶石有天然形成和人工合成兩種，其化學(xué)式為MgAL2O4或者M(jìn)goAL2O3。尖晶石理論含量為：MgO=28.3%M,AL2O3=71.7%。
Brief introduction of spinel:
Spinel is one of the rare minerals in nature, which must be made by artificial synthesis. All the aluminum magnesium spinel used in industry is synthetic. The two main bs for the synthesis of Al Mg spinel are the sintering b and the electrofusion b. Most spinel material is made from high purity alumina and chemical synthesis of Magnesium Oxide, which in shaft kiln sintering and electric melting in arc furnace. Al Mg spinel belongs to a kind of aluminum and magnesium oxide, its main components are alumina and Magnesium Oxide. Al Mg spinel has two kinds of natural bation and artificial synthesis, the chemical bula is MgAL2O4 or MgoAL2O3. The theoretical content of spinel is: MgO=28.3%M, AL2O3=71.7%.
