Description

一种热膨胀金属
技术领域
本发明涉及一种热膨胀金属。
背景技术
1995年,俄罗斯奥尔登堡大学的生物学家梅格列特在研究一种叫蓼的一年生草本植物时,意外地发现蓼的叶子中含有异常高的锌、铅、镉等金属。这是否表明蓼有从土壤中吸收这些金属的“嗜好呢”?于是他带着这个疑问,在一些被锌、铅、镉之类金属污染过的土地上种了大量的蓼。这些蓼长得非常茂盛,叶子又大又厚,结果在1 公顷的土地上,一个季节就收获了大量的蓼。梅格列特将蓼草放入800 ℃的炉子里烧,草化为灰烬,结果从中得到了1.3千克镉、23千克铅、322千克锌。最近,德国奥尔登大学的一个试验小组已在一处废金属堆放场引种俄罗斯大蓼获得成功,现在该试验小组已从德国各地尤其是环保组织接到了大量订单,同时还为推广这项研究成果专门成立了一家商业性公司。它的业务活动已引起德国军事部门的很大兴趣,因为历史上的各种军事演习场包括二战时期用作化学武器仓库的地方都有待改造,消除污染,公司方面业已应约在那些地方种下了大蓼,以净化环境,回收有害金属。还有文献报到,美国加利福尼亚的专家们通过研究发现,野生芥菜有从土壤中蓄积镍的功能,他们把种植的半公顷的野生芥菜杆割下来,晒干再烧成灰,每100克芥菜灰中获得了15-20克镍。他们目前正着手培育蓄积金属能力更强的芥菜新品种,预计可以从每平方米的土地上获取12克镍。尽管通过这种方式获取镍的效果远不及其它办法,但对环境无任何污染。科学研究证明,植物在千百万年漫长的进化演变过程中,已经练就了一身非凡绝招,许多植物有累积某些金属元素的能力。如堇菜好锌、香薷含铜比较丰富、烟草含铀特别多,还有紫云英含硒、苜蓿含钽、石松含锰格外丰富。生长在含黄金特别多的土壤中的玉米或木贼草,烧成灰,每吨竟可以提取到10克黄金。有些植物能累积稀有金属,如铬、镧、钇、铌、钍等,被称为“绿色稀有金属库”。它们对稀有金属的聚集能力要比一般植物高出几十倍、成百倍,甚至上千倍。比如铬,在一般植物中用光谱检测也很难发现,而凤眼兰却能在根上累积铬,其含量可达到0.13%。这一系列的发现引起了科学家们的极大兴趣,被人们称为“绿色冶金”技术。专家预言如果这一成果取得突破性的进展,人类将有可能通过种植植物来获得所需的金属,同时还可以改善遭受人类破坏的环境。
发明内容
本发明的目的在于提供具有耐腐蚀性、抗氧化性和热膨胀性的一种热膨胀金属。
本发明的技术方案是:一种热膨胀金属,包括硅、硒、碲、砷、硼、锡、锑、铋和其他杂质等元素,各元素重量配比为硅占1%-19%,硒占2%-3%,碲占1%-5%,砷占18%-20%,硼占14%-17%,锡占20%-22%,锑占13%-14%,铋占4%-6%,其他杂质占9%-12%。
在本发明一个较佳实施例中,所述其他杂质包括镉和汞。
在本发明一个较佳实施例中,所述热膨胀金属各成分重量配比为硅占13%,硒占2%,碲占3%,砷占19%,硼占15%,锡占21%,锑占13%,铋占5%,其他杂质占10%。
本发明的一种热膨胀金属,具有耐腐蚀性、抗氧化性和热膨胀性的效果。
具体实施方式
下面结合对本发明的较佳实施例进行详细阐述,以使本发明的优点和特征能更易于被本领域技术人员理解,从而对本发明的保护范围做出更为清楚明确的界定。 
在一实施例中,一种热膨胀金属,包括硅、硒、碲、砷、硼、锡、锑、铋和其他杂质等元素,各元素重量配比为硅占1%-19%,硒占2%-3%,碲占1%-5%,砷占18%-20%,硼占14%-17%,锡占20%-22%,锑占13%-14%,铋占4%-6%,其他杂质占9%-12%,所述其他杂质包括镉和汞。
进一步说明,所述热膨胀金属各成分重量配比为硅占13%,硒占2%,碲占3%,砷占19%,硼占15%,锡占21%,锑占13%,铋占5%,其他杂质占10%。
根据不同需求可按照不同比例进行调试,从而达到不同的使用效果,金属材料在所定的冷、热加工条件下表现出来的性能。金属材料工艺性能的好坏,决定了它在制造过程中加工成形的适应能力。由于加工条件不同,要求的工艺性能也就不同,如铸造性能、可焊性、可锻性、热处理性能、切削加工性等。所谓使用性能是指机械零件在使用条件下,金属材料表现出来的性能,它包括力学性能、物理性能、化学性能等。金属材料使用性能的好坏,决定了它的使用范围与使用寿命。在机械制造业中,一般机械零件都是在常温、常压和非常强烈腐蚀性介质中使用的,且在使用过程中各机械零件都将承受不同载荷的作用。金属材料在载荷作用下抵抗破坏的性能,称为力学性能(过去也称为机械性能)。金属材料的力学性能是零件的设计和选材时的主要依据。外加载荷性质不同(例如拉伸、压缩、扭转、冲击、循环载荷等),对金属材料要求的力学性能也将不同。常用的力学性能包括:强度、塑性、硬度、冲击韧性、多次冲击抗力和疲劳极限等。本发明提供一种热膨胀金属,具有耐腐蚀性、抗氧化性和热膨胀性的效果。
本发明的具体实施方式,但本发明的保护范围并不局限于此,任何熟悉本领域的技术人员在本发明所揭露的技术范围内,可不经过创造性劳动想到的变化或替换,都应涵盖在本发明的保护范围之内。因此,本发明的保护范围应该以权利要求书所限定的保护范围为准。
