查询词典 float copper

First firing of raw materials are usually basic glaze frit, in the process of production need to add metal oxides, metal ions is also a special color of the enamel glaze color, or as a gel, or suspension-like particles of the dispersion or absorption of light and color, for example, cobalt oxide blue or purple, blue green copper oxide, cobalt oxide copper oxide mixture is significant blue, red cuprous oxide, nickel oxide in the potassium content of the glaze was red, in the sodium yellow glaze of green, if used alone was brown iron oxide, cobalt oxide and manganese dioxide are combined black or dark brown.

通常是先将原料烧成基本釉的熔块，在制作的过程中再加入需要的金属氧化物，也就是以金属离子特具的颜色而使珐琅釉呈色，或成为胶状，或悬浮状的粒子对光线的色散或吸收而呈色，例如氧化钴呈蓝或紫色、氧化铜呈蓝绿色、氧化铜混和氧化钴则显青色、氧化亚铜呈红色、氧化镍在含钾之釉中呈红色、在含钠之釉中呈黄绿色，又如氧化铁单独使用呈褐色，与氧化钴及二氧化锰合用则呈黑色或黑褐色。

Ti element is found to aggregate, forming an ultra-fine reaction layer in the active filler metal-ceramic joint after 260℃/24hr aging treatment. Two different-color intermetallic compounds are observed in the interface of active filler metal-copper. One is Cu6Sn5 , which is closer to active filler metals;the other is Cu3Sn, which is closer to the copper substrate.

接合后之试片，经260℃/24hr时效反应后，发现Ti元素聚集於焊料与陶瓷界面处形成一层极薄的反应层且发现在焊料与铜之反应界面有了明显颜色不同之两层介金属层生成，靠近焊料端的介金属层为Cu6Sn5，Cu片端的是Cu3Sn；而Cu6Sn5化合物从原本未时效10μm成长为25μm。
