Crystallization Temperature of CaO-SiO_2-Na_2O-CaF_2-Al_2O_3-MgO;

The effect of crystallization temperatures(100 ℃~140 ℃) on the production of β crystal form in isotactic polypropylene nucleated by pimelic acid,magnesium pimelate and aluminium pimelate respectively had been studied in this paper.

The effects of R,Na2CO3 content,CaF2 content,Al2O3 content and MgO content on crystallization temperature were determined.

Effect of manufacturing technologies of ingot on the recrystallization temperature of pure tantalum plate;

Influences of rare earth elements on recrystallization temperature of pure copper and BFe10-1-1 alloy

The results show that the high temperature mechanical properties of molybdenum wire have been improved markedly by Si、Al、K doping; the recrystallization temperature of molybdenum wire has been increased by 550～600℃ via Si、Al、K doping which generates an interlocked grain structure; the strengthening phase of Si、Al、K doped molybdenum wire is not only the K.

According to the problems on bottom running method and the narrow crystallization range of this alloy that can freeze layer-by-layer,the measure named pouring horizontally and cooling vertically method was put forward.

Testing results indicated that DSC fusion curve of samples prepared by means of gradient isothermal crystallization revealed multiple fusion peaks, good repetition of testing results, high differentiation between different samples facilitating a reliable fast appraisal of unknown quality of g.
