Sb can combine with Cu and P to form a low melting point compound which lowers the melting point of binary Cu-8P eutectic alloy by nearly 200℃. Bi and Cu can create compounds with low melting point(270℃) distributing at the boundaries and that is the reason why the melting point of (Cu-8P)-Bi is lower than that of binary Cu-8P eutectic alloy. The eutectic cluster can be refined with the addition of Fe, and that is the reason why the addition of Fe can decrease the melting point of Cu-8P alloy. Two means of decreasing the melting point of Cu-8P are found.
一定量的Sb与Cu, P形成低熔点相,从而大幅降低了Cu-8P合金的熔点,使其熔点降低近200℃;加入少量Bi后, Bi与Cu在共晶团晶界上形成熔点为270℃左右的低熔点化合物,且Bi的加入明显细化Cu-8P合金共晶团,从而使Cu-8P合金的熔点降低;加入Fe能明显细化Cu-8P合金的共晶团,使层片间距由8μm减为2μm以下,并使共晶团由层片状向短棒状转变,虽然Fe与Cu形成熔点为806℃的高温相,但Fe的细化作用使得Cu-8P合金的熔点降低,但降低幅度不大。

When different materials mixed,the mixture will have a mixed melting point of mixture ,and the mixed melting point of mixture is different from the intersoluble solutions.we separate the intersoluble solutions by different melting piont of intersoluble solutions when separate temperature is flexible temperatureThese intersoluble solutions different in melting point, the method would make the high melting point material became solid while the low melting point material still be liquid by adopting cryogenic treatment with stirring so as to meet the requirement of purifying these two solutions.
这种分离方法的特点是利用两种互溶性物质具有不同的熔点,通过低温处理,并同时加以搅拌,震荡,使高熔点物质和低熔点物质形成固液混合体,再对固液混合体进行离心分离得到高熔点的固体和低熔点的液体,从而达到浓缩、提纯两种物质目的。

The results of the rule of law with ordinary methylation by formaldehyde Veratryl three groups the average weight of 2.5609g, the average yield was 91.31%, the melting point of the three groups were 42.4 ~ 44.8 ℃, 41.5 ~ 45.2 ℃, 41.7 ~ 44.3 ℃, from the results of we can see that the three groups of the melt from the melting point greater than that which the product of the by-product of the detection of the melting point have a certain impact; and the legal system with microwave radiation by an average of Veratrum aldehyde quality 1.4016g, the average yield was 93.23 %, melting point of the three groups were 41.8 ~ 43.2 ℃, 41.3 ~ 42.6 ℃, 41.6 ~ 43.5 ℃, melting away from the three groups as compared with ordinary methods of measuring the melt-out from the small.
结果 用普通甲基化法制出来的三组藜芦醛平均质量为2.5609g,平均产率为91.31%,三组的熔点分别为42.4~44.8℃,41.5~45.2℃,41.7~44.3℃,从结果可以看出,三组熔点的熔距都比较大,证明产物当中的副产物对熔点的检测有一定的影响;而用微波辐射法制出来的藜芦醛平均质量为1.4016g,平均产率为93.23%,三组熔点分别为41.8~43.2℃,41.3~42.6℃,41.6~43.5℃,三组熔距较普通方法测出来的熔距小。

melting point:熔点
不到熔点为什么金属会燃烧 熔点(melting point) 熔点是固体将其物态由固态转变(熔化)为液态的温度. 进行相反动作(即由液态转为固态)的温度,称之为凝固点. 与沸点不同的是,熔点受压力的影响很小. 晶体融化时的温度叫做熔点. 物质有晶体和非晶体,
