. It has more available oxygen than does liquid oxygen on a volume basis. Lithium perchlorate has a specific gravity of 2.429, which is heavier than water, and is water soluble. It is a dangerous fire and explosion risk in contact with organic materials and is a irritant to skin and mucous membranes. The primary use of lithium perchlorate is as a solid rocket propel-lant. Chlorates are atrong oxidizing agent. When heated, they give up oxygen readily Contact with organic or other combustible materials may cause spontaneous combustion or explosion.
