the experimental results showed that 80% of the niobium mineral entered the tailings with the roasting temperature of 1200 ℃, while 90% entered dri in 1300 ℃ with adding fluxing agent ts2 10%.
而1300 ℃时添加助熔剂ts2用量10%条件下,90%铌矿物在直接还原焙烧- 磁选得到还原铁产品中富集。
element p can also act as a fluxing agent to decrease the surface tension and viscosity of the melt, thereby improve the sintered densification and the microstructural homogeneity.
p元素亦能充当稀释剂而降低熔体粘度及表面张力,从而改善烧结致密度及组织均匀性;
the performance of leadless and cadmiumless fluxing agent for overglaze colors was investigated through orthogonal experiments.
应用正交试验法,研究了堿金属氧化物及氟化物对环保型无铅釉上彩熔剂性能的影响。
when solder bumps (22) on the die are reflowed, the fluxing agent acts to remove any oxides present on the solderable surfaces of the substrate or the die.
当管芯上的焊料突点(22)被回流时,该助焊剂的作用是清除基板或管芯的可焊接表面上存在的任何氧化物。
