| Large amount of different magnesium silicate raw materials are
available in the region of Karnataka and Tamilnadu, India, which
did not get a wide commercial acceptance for the production of
refractories even today. One such material is olivine, a by-product
from the magnesite mines, which can be used for the manufacturing
of forsterite refractories, a substitute for magnesite
refractories in many applications. After chemical analysis of for
sterite, compositional adjustment was done by adding dead
burned magnesite to maximize the forsterite phase and to
convert the impurities to high temperature compounds. Uniaxially
pressed products of such compositions were sintered in the
temperature range of 1200° - 1600 C and characterized for
various refractory properties. |
