Bismuth resources, reserves and productionMetalpedia
Bismuth resources, reserves and production; Occurrence in nature; Bismuth, at an estimated 8 parts per billion by weight, ranks 69th in elemental abundance in the Earth’s crust and is about twice as abundant as goldWorld reserves of bismuth are usually based on bismuth content of lead resources because bismuth production is most often a byproduct of processing lead ores; in China, bismuth thermal conductivity, bismuth telluride is a semiconductor with ceramiclike properties These ceramiclike properties contribute to defect formation during laser processing Bismuth telluride has a low thermal conductivity (2 W m–1 K–1 at 25 °C) that inhibits heat flow between the melt pool and surrounding material during LPBFNano‐ and Micro‐Structures Formed during Laser Bismuth 元素符号 Bi 原子量 20898 原子序数 83 元素类别 金属元素 周 期 第六周期 族 V A 电子排布 [Xe] 4f 14 5d 10 6s 2 6p 3 电负性 202（鲍林标度） CAS登录号 EINECS登录号 2311774 外 观 银白色至粉红色的金属 密 度 98 g/cm³ 沸 点铋（金属元素）百度百科 Baidu Baike
