Dense liquid is an organic liquid with high density or an aqueous solution of inorganic salt. Dense suspension liquid is a mixed suspension liquid of densifying material (mostly the separated concentrate of magnetite and ferrosilicon) and water. Dense liquid is toxic and costly, so it is only used in laboratories.
