pressing powder

Novel rare-earth contained bismuth telluride thermoelectric materials were prepared by solvothermal synthesis at 180 ℃ using bismuth chloride, tellurium powder and lanthanum chloride or oxide as starting materials, and the following hot uniaxial pressing ( HUP), 400 ℃, at 50() MPa for 1h.

以氯化铋、碲粉、氯化镧或氧化镧为原料，采用180℃溶剂热合成和400℃、50MPa、1h热压技术制备了含稀土的新型Bi2Te3基热电材料。

During using a universal adjustable die set, the floating force, floating amount and powder-filling amount may be adjustable whenever necessary in pressing.

使用通用可调式模架，在压制过程中可根据需要随时调整阴模的浮动力、浮动量和装粉量。

The lower temperature of powder hot pressing process restricted or reduced the reaction between the quasicrystalline particle and metal matrix. Except the reaction product of quasicrystalline approximant Al_ 13 Fe_4, there was the oxidation of MgAl_2O_4 on Al_ 63 Cu_ 25 Fe_ 12 particle edge.

粉末热压复合过程中的较低温度限制或减缓了准晶颗粒与基体金属之间的反应，反应层的反应产物除了准晶类似相Al13Fe4外，还存在一定的MgAl2O4氧化物。

The utility model relates to an adjustable core bar for the dry isostatic pressing forming machine which is especially suitable to produce the special-shaped ceramic flan, the powder metal pipe, ect.

本实用新型涉及一种干袋法等静压成型机用的可调芯杆，其造型特别适合生产异型陶瓷素坯管、粉末金属管等。
