The results showed that:①the crystalline phases are mainly the cuspidine, wollastonite and gehlenite with nepheline, fluorite and olivine also found in some samples under the experimental conditions;②with the bacisity and CaF_2 content increased, crystalline proportion of mold flux rises .

熔融保护渣在MoSi2高温电阻炉内以2℃/min降温速率冷却至室温，制成薄片，采用岩相显微镜分析保护渣的结晶矿相·结果表明：在本实验条件下，结晶矿相主要有枪晶石，硅灰石，黄长石，个别渣样有霞石，萤石，橄榄石；增大保护渣碱度，能促进保护渣结晶；随着渣中CaF2，Na2O，K2O和Li2O质量分数的增大，保护渣结晶化率增大；随着渣中Al2O3，MgO，BaO和MnO质量分数的增大，保护渣结晶化率减小

The reason that the micro spar the performance surpasses the natural granite, the marble, the synthesis stone and the artificial marble, contains the material ingredient and the formation with him related; The granite is by granulometric compositions and so on quartz, feldspar, mica.

微晶石之所以性能优于天然花岗石、大理石、合成石及人造大理石，与他所含的物质成分及成型有关；花岗石是由石英、长石、云母等颗粒组成。
