纳米氧化钨的认识,制备及应用
纳米氧化钨的认识，制备及应用【什么是氧化钨？】氧化钨（Tungsten trioxide），分子式为WO3，分子量为231.85。
是一种钨酸酐，是钨酸盐类产品，氧化钨包括三氧化钨和二氧化钨，实际工业生产中并没有二氧化钨的制品。
三氧钨盐根据三氧化钨的含量不同分为钨酸，钨酸钠，钨酸钙，仲钨酸铵，偏钨酸铵等产品。
纳米氧化钨的颜色，在W - O系中，存在WO3、WO2.9、WO2.72，WO2等钨氧化物。
WO3(黄) -- WO 2.90 (蓝) - WO 2.72 ，(紫) 也就是钨有三种稳定的氧化物：黄色氧化物（WO3，VK-WO3万景供应），蓝色氧化物（WO2.90，VK-WO29万景供应），紫色氧化物（WO2.72，VK-WO27万景供应）。
【氧化钨的制备方法】1、钨酸铵法钨精矿经氢氧化钠碱解，用盐酸中和，再与氯化铵作用，生成钨酸铵，再加人盐酸进行酸解反应，生成钨酸，然后经过焙烧分解、粉碎，得到三氧化钨。
2、钨酸盐的盐酸分解法。
将钨酸钠Na2WO4、钨酸钙CaWO4等钨酸盐的饱和水溶液加热，按摩尔比将溶液慢慢地滴加到2～3倍过量的沸腾浓盐酸中。
按上述反应沉淀出黄色钨酸。
这时如果滴加速度过快或液温下降，则容易生成悬浮状或胶体状沉淀，给下一步的处理带来困难。
滴加后在水浴上连续加热1h，沉淀变得易于过滤。
静置后用5%硝酸铵水溶液洗涤几次，将Cl-完全除去。
过滤后在120℃下干燥，最后升温到600℃钨酸则完全脱水变成三氧化钨。
3、仲钨酸铵的热分解法。
将用重结晶法提纯的仲钨酸铵(NH4)10W12O41·11H2O装入瓷坩埚中，加热到约400℃以上时，氨挥发出去则得三氧化钨。
【细分纳米氧化钨的形态和应用】一、纳米氧化钨--黄钨（VK-WO3, 50nm,万景供应）三氧化钨，黄色粉末。
不溶于水，溶于碱，微溶于酸。
用于制高熔点合金和硬质合金，制钨丝和防火材料等。
可由钨矿与纯碱共熔后加酸而得。
三氧化钨是淡黄色斜方晶系结晶粉末。
运放关键参数及选型原则之欧阳美创编
运放参数解释及常用运放选型集成运放的参数较多，其中主要参数分为直流指标和交流指标，外加所有芯片都有极限参数。
本文以NE5532为例，分别对各指标作简单解释。
下面内容除了图片从NE5532数据手册上截取，其它内容都整理自网络。
极限参数主要用于确定运放电源供电的设计（提供多少V电压、最大电流不能超过多少），NE5532的极限参数如下：直流指标运放主要直流指标有输入失调电压、输入失调电压的温度漂移（简称输入失调电压温漂）、输入偏置电流、输入失调电流、输入偏置电流的温度漂移（简称输入失调电流温漂）、差模开环直流电压增益、共模抑制比、电源电压抑制比、输出峰-峰值电压、最大共模输入电压、最大差模输入电压。
NE5532的直流指标如下：输入失调电压Vos输入失调电压定义为集成运放输出端电压为零时，两个输入端之间所加的补偿电压。
输入失调电压实际上反映了运放内部的电路对称性，对称性越好，输入失调电压越小。
输入失调电压是运放的一个十分重要的指标，特别是精密运放或是用于直流放大时。
输入失调电压与制造工艺有一定关系，其中双极型工艺（即上述的标准硅工艺）的输入失调电压在±1~10mV之间；采用场效应管做输入级的，输入失调电压会更大一些。
对于精密运放，输入失调电压一般在1mV 以下。
输入失调电压越小，直流放大时中间零点偏移越小，越容易处理。
所以对于精密运放是一个极为重要的指标。
输入失调电压的温度漂移（简称输入失调电压温漂）ΔVos/ΔT输入失调电压的温度漂移定义为在给定的温度范围内，输入失调电压的变化与温度变化的比值。
这个参数实际是输入失调电压的补充，便于计算在给定的工作范围内，放大电路由于温度变化造成的漂移大小。
一般运放的输入失调电压温漂在±10~20μV/℃之间，精密运放的输入失调电压温漂小于±1μV/℃。
输入偏置电流Ios输入偏置电流定义为当运放的输出直流电压为零时，其两输入端的偏置电流平均值。

放入炉中加热。
2：热加工 哈氏 B-2 合金可以在 900~1160℃范围内进行热加工，加工过后应该以水淬火。为 了确保有最好的耐蚀性能，热加工过后应该退火。 3：冷加工 冷加工的哈氏 B-2 合金必须经过固溶处理，由于其具有比奥氏体不锈钢高得多的 加工硬化率，所以成形设备要细心考虑。如果执行了冷成形工艺，那么有必要进行级间 退火。 冷加工变形量超过 15%时，使用前要固溶处理。 4：热处理 固溶热处理温度要控制在 1060~1080℃之间，之后进行水冷淬火或材料厚度在 1.5mm 以上时可以快速空冷以获得最好的耐蚀性能。在任何加热操作过程中，材料的 表面清洁均要有预先的防范。哈氏合金材料或设备部件在进行热处理时要注意以下一些 问题：为了防止设备部件热处理变形，应采用不锈钢加强环；对装炉温度、加热和冷却 时间应严格控制；装炉前，对热处理件进行预处理，防止产生热裂纹；热处理后，对热 处理件 100%PT；在热处理过程中如产生热裂纹，经过打磨消除后需补焊者，要采用专 门的补焊工艺。 5：除垢 哈氏 B-2 合金表面的氧化物和焊缝附近的污点都要以精细的砂轮等打磨干净。 由于哈氏 B-2 合金对氧化性介质比较敏感，因此酸洗过程中会产生较多的含氮元 素的气体。 6：机加工 哈氏 B-2 合金要以退火状态进行机加工，对它的加工硬化要有清醒的认识，例如： 相对于标准奥氏体不锈钢要采用较慢的表面切削速度，对于表面的硬化层要采用较大的 进刀量，并使刀具处于连续的工作状态。 7：焊接 哈氏 B-2 合金焊缝金属及热影响区由于易析出β相而导致贫 Mo，从而易于产生晶 间腐蚀，因此，哈氏 B-2 合金的焊接工艺应谨慎制定，严格控制。一般焊接工艺如下： 焊材选用 ERNi-Mo7；焊接方法 GTAW；控制层间温度不大于 120℃；焊丝直径φ2.4、 φ3.2；焊接电流 90~150A。同时，施焊前，焊丝、被焊接件坡口及相邻部位应进行去 污脱脂处理。 哈氏 B-2 合金热传导系数比钢小得多，如选用单 V 型坡口，则坡口角度要在 70°

运放关键参数及选型原则
运放参数解释及常用运放选型集成运放的参数较多，其中主要参数分为直流指标和交流指标，外加所有芯片都有极限参数。
本文以NE5532为例，分别对各指标作简单解释。
下面内容除了图片从NE5532数据手册上截取，其它内容都整理自网络。
极限参数主要用于确定运放电源供电的设计（提供多少V电压、最大电流不能超过多少），NE5532的极限参数如下：直流指标运放主要直流指标有输入失调电压、输入失调电压的温度漂移（简称输入失调电压温漂）、输入偏置电流、输入失调电流、输入偏置电流的温度漂移（简称输入失调电流温漂）、差模开环直流电压增益、共模抑制比、电源电压抑制比、输出峰-峰值电压、最大共模输入电压、最大差模输入电压。
NE5532的直流指标如下：输入失调电压Vos输入失调电压定义为集成运放输出端电压为零时，两个输入端之间所加的补偿电压。
输入失调电压实际上反映了运放内部的电路对称性，对称性越好，输入失调电压越小。
输入失调电压是运放的一个十分重要的指标，特别是精密运放或是用于直流放大时。
输入失调电压与制造工艺有一定关系，其中双极型工艺（即上述的标准硅工艺）的输入失调电压在±1~10mV之间；采用场效应管做输入级的，输入失调电压会更大一些。
对于精密运放，输入失调电压一般在1mV以下。
输入失调电压越小，直流放大时中间零点偏移越小，越容易处理。
所以对于精密运放是一个极为重要的指标。
输入失调电压的温度漂移（简称输入失调电压温漂）ΔVos/ΔT输入失调电压的温度漂移定义为在给定的温度范围内，输入失调电压的变化与温度变化的比值。
这个参数实际是输入失调电压的补充，便于计算在给定的工作范围内，放大电路由于温度变化造成的漂移大小。
一般运放的输入失调电压温漂在±10~20μV/℃之间，精密运放的输入失调电压温漂小于±1μV/℃。
输入偏置电流Ios输入偏置电流定义为当运放的输出直流电压为零时，其两输入端的偏置电流平均值。
