摘要:
Low bulk density products containing at least 10% Wegscheider's Salt, by weight, in needlelike form are produced from sodium bicarbonate by heating in the presence of a slow inert gas stream an aqueous feed mixture comprising, by weight, at least about 50% sodium bicarbonate and about 15 to 30% Wegscheider's Salt.
