| The effect of impurities present in some natural ma,gnesites on the sintering
process and crystal growth of periclase at high temperatures, as well as the nature
and distribution of matrix minerals and pores in the sz'ntered magneS'ites hm•e been
examined by microscopic and X -ray diffraction studies.
Iron oxide P'romotPs sintering of ma,gnPsitPs and crystal growth of periclase.
Lime does not aduersely affat the sintning process, but has a definite retardŁng
effect on the crystal growth of periclase at high temperatures. Sint!ering behaviour
of magnPsite rich in silica dors not materially differ from that of a rPlatively pu,-e
magnesite but silica acts as a powerful crystal growth promoter for periclase. |
