硅线石矿是一种高铝耐火材料。随着冶金工业的发展,硅线石的利用已提到日程上来了。一、物质组成研究矿石含硅线石34～37%,微斜长石32—36%,赤铁矿7～8%,石英5%,黑云母1%。在硅线石中束禾状集合体占65%,针柱状单晶体占35%。当束禾状或蒿束状硅线石集合体相当富集时即构成束禾状或蒿束状结构。其次为压碎结构。矿石中矿物重结晶程度较高,一般为中粗粒变晶。等向粒状微斜长石较发育,并含有相当数量的针柱状、毛发状硅线石和叶片状白云母,均呈断续定向排列,并且有分别聚集相间分布的特征。硅线石束禾状集合体粒度为0.4×1.5～1.5×3毫米,硅线石针
Sillite is a high-alumina refractory. With the development of the metallurgical industry, the utilization of sillimanite has been mentioned on the agenda. First, the material composition of the ore ore containing silicon 34% ~ 37%, micro-plagioclase 32-36%, hematite 7-8%, quartz 5%, biotite 1%. Holstein-like aggregates account for 65% of the sillimanite and 35% of the needle-shaped single crystals. When the Wo-like or Artemisia bundle-like sillimanite assembly is rich when the composition that beam Wo-like or Artemisia bundle structure. Followed by crushed structure. Ore mineral recrystallization degree is higher, usually in the coarse grains of crystal. Isotropic graded plagioclase is more developed, and contains a considerable number of acicular, hairy sillimanite and leaf-shaped muscovite, were intermittent directional arrangement, and have gathered the characteristics of the phase distribution. Silicone beam Wo-shaped aggregate size of 0.4 × 1.5 ~ 1.5 × 3 mm, sillimanite needle
