Silicon Carbide: Smaller, Faster, Tougher
Meet the material that will supplant silicon in hybrid cars and the electric

Some technological revolutions are flashy, and some are almost invisible. We
’re quite familiar with the flashy ones; they’ve given us powerful
computers we can hold in the palms of our hands, devices that can pinpoint
our locations by way of orbiting satellites, and the ability to bank and

What Happened To GaN And SiC?
Early predictions were overly optimistic, but these technologies are
starting to make inroads.
About five years ago, some chipmakers claimed that traditional silicon-based
power MOSFETs had hit the wall, prompting the need for a new power
transistor technology.
At the time, some thought that two wide-bandgap technologies—gallium
nitride (GaN) on silicon and silicon carbide (SiC) MOSFETs—would displace
the ubiquitous power MOSFET. In addition, GaN and SiC were suppos... 阅读全帖

NEW YORK Union Carbide Corp. has fended off a lawsuit brought on behalf of victims of the 1984 chemical leak in Bhopal, India, as a U.S. federal judge threw out the claims for a second time.
.
A U.S. appeals court had reinstated some of the claims against the unit of Dow Chemical Co. stemming from the world's worst industrial accident, which killed more than 6,000 people. U.S. District Judge John Keenan, who had dismissed the class-action
suit in 2000, ruled Tuesday that the 1999 suit was filed

工业用电石不是纯净物,反应之后确实会有有毒气体释放出来。
The pure material is colorless, however pieces of technical-grade calcium
carbide are grey or brown and consist of about 80–85% of CaC2 (the rest is
CaO (calcium oxide), Ca3P2 (calcium phosphide), CaS (calcium sulfide), Ca3N2
(calcium nitride), SiC (silicon carbide), etc.). In the presence of trace
moisture, technical-grade calcium carbide emits an unpleasant odor
reminiscent of garlic.[4]

嗯,一时没想到, 你这个会贵一点,也就20几刀,你的属于上等机子,用到80V的电路
板,80V的silicon nitride 点火器。低端furnace 是120V电路板,用传统的120V的

silicon nitride 点火器它会有信息反馈回电路板,LED codes list 上许多厂牌都有
点火器的信息。
silicon carbide igniter 就没有。
所以第一步得相信电路板,先换个ignitor.

CREE大家知道的就是LED,它除了LED元件本身,还做灯泡灯具。
昨天想起两年前做过一个电路效率为什么那么好,仔细一看原来用了一只CREE的
silicon carbide diode。这种二极管在要求高效率的地方特别有用,如PC电源,电视等。当然现在大众化的产品都不用这种diode,但随着各种标准如engergy star, 80 plus之类的越来越高的要求,这种diode的需求会逐渐增加。CREE在silicon carbide diode方面的竞争对手目前只有STMicroelectronics和Infineon。

来自主题: Military版 - 死1万5千人,赔了4亿七千万美刀
印度博帕尔(Bhopal)灾难是历史上最严重的工业化学意外,死伤者数以十万计,对环境
更造成难以补救的破坏。1984年12月3日晚上,联合碳化公司(Union Carbide)在印度
Madhya Pradesh的博帕尔的化工厂发生毒气泄漏事件,估计导致3,500至7,500人实时死亡。到现时为止意外已导致16,000人死亡,另外有几十万名居民的健康受到不同程度的影响,他们除了肺部功能受到损害,神经、肠胃、生殖及免疫系统亦受到伤害。
经过五年的法庭诉讼的争论,联合碳化公司最终在89年与印度政府达成协议,只付出了
4亿7千万美元,就解决了所有的民事追讨费用。这笔款项看似非常巨大,但事实上每个
受害人平均只能拿取约370至533美元的赔偿,这还不足以支付伤者5年的医疗费用。世
界历史上最严重的工业意外也只不过令联合碳化公司需要付出每股48美元的代价。

印若抵制奥运 英国首相:会很难过
(2012-03-11 2100)
(综合讯)据中央社报道,英国首相卡梅伦表示,若印度因为与1984年博帕尔毒气
外泄事件有关的陶氏化学公司提供赞助,而抵制伦敦奥运,他将“非常难过”。但他认
为,抵制事件不会影响两国关系。
中印度马德雅省(Madhya Pradesh)省会博帕尔(Bhopal)的联合碳化物印度分公
司(Union Carbide India Ltd.)杀虫剂厂,1984年12月2日深夜至3日清晨发生异氰酸
甲酯毒气自储存槽外泄事故。
事件造成3500人立即丧生;因吸入毒气或饮用遭污染水源,死亡人数数周后再增1
万5250人。据信后来陆续造成逾55万人死于与化学中毒有关的肺癌、肾衰竭、肝病等疾
病,堪称史上最严重的工业意外之1。
陶氏化学公司在2001年收购联合碳化物公司,坚称后者已于1989年支付4亿7000万
美元,向印度政府结清赔偿,拒绝对1984年的毒气外泄事故负任何责任。

This is the sequence of the nuclear criticality accident from "Fat Man and
Little Boy" with John Cusack. This storyline was based on two real accidents

brilliant scientists.

Radiation-hardening techniques[edit]
Physical:
Hardened chips are often manufactured on insulating substrates instead of
the usual semiconductor wafers. Silicon dioxide (SOI) and sapphire (SOS) are
commonly used. While normal commercial-grade chips can withstand between 50
and 100 gray (5 and 10 krad), space-grade SOI and SOS chips can survive
doses many orders of magnitude greater. At one time many 4000 series chips
were available in radiation-hardened versions (RadHard).[3]
