性状一
整个晶体的原子排列是有规则、有周期性的,其结构方向一致,性脆易裂。熔点1410℃。沸点2477℃。相对密度2.336。莫氏硬度7.0。晶格常数5.42×10-10m。原子距2.252×10 -10m。
性状二
具有灰色金属光泽的晶体。相对密度2.32~2.34。熔点1410℃。沸点2355℃。溶于氢氟酸和硝酸的混酸中,不溶于水、硝酸和盐酸。硬度介于锗和石英之间,在室温下质脆,切割时易碎裂。加热至800℃以上即可延长,1300℃时显出明显变形。常温下不活泼,高温下与氧、氮、硫等引起反应。在高温熔融状态下,具有较大的化学活性,几乎能与任何材料起作用。具有半导体性质,是极为重要的优良半导体材料,但微量的杂质即可大大影响其导电性。
所属类别

用途与作用二
用作制备单晶硅的原料。
合成工艺与制法一
三氯氢硅法将干燥的硅粉加入合成炉中,与通人的干燥氯化氢气体在280~330℃有氯化亚铜催化剂存在下进行氯化反应,反应气体经旋风分离除去杂质,再用氯化钙冷冻盐水将气态三氯氢硅冷凝成液体,经粗馏塔蒸馏和冷凝,除去高沸物和低沸物,再经精馏塔蒸馏和冷凝,得到精制三氯氢硅液体。纯度达到7个“9”以上、杂质含量小于1×10-7,硼要求在0.5×10-9以下。提纯后的三氯氢硅送人不锈钢制的还原炉内,用超纯氢气作还原剂,在1050~1100℃还原成硅,并以硅芯棒为载体,沉积而得多晶硅成品。其反应式如下:
H2+C12→2HCl
S+3HCl→SiHC13+H2
SiHCl3+H2→Si+3HCl
合成工艺与制法二
工业生产有坩埚直拉法、悬浮区熔法、中子嬗变掺杂法。
坩埚直拉法拉晶前先将设备各部件、合金石英坩埚、硅多晶和籽晶进行清洁处理。
将硅多晶破碎除去石墨,经丙酮去油后,进行化学清洗,用无离子水洗至中性,再经超声波清洗,红外干燥,配料及掺杂,加入单晶炉的合金石英坩埚中,再经抽真空、熔化,在流通的氩气氛下,人工引晶放肩和收尾。晶体的等径生长过程中,需根据情况适当调节功率,使其获得直径均匀的产品,经检测、称量,制得硅单晶成品。
悬浮区熔法先将设备和原料清洁处理,把硅多晶切断,磨后用丙酮去油,进行化学清洗,用无离子水洗至中性,再经超声波清洗,红外干燥,配料和掺杂,装炉,抽真空或充氩气。在氩气下高频加热进行区熔提纯单晶。预热、引晶、放肩、等径、收尾等过程,由人工控制。再经检测、称量,制得硅单晶成品。
