• Kinetics and mechanisms of reactions of HgI<SUB>2</SUB>, HgBrI, or HgBr<SUB>2</SUB> with CuI were studied in the solid state. Mercury(II) halides react <I>via</I> vapor phase, and reactions proceed through counter diffusion of Cu<SUP>+</SUP> and Hg<SUP>2+</SUP>. X-Ray and chemical analyses indicate that powdered Cul gives Cu<SUB>2</SUB>HgI<SUB>4</SUB> when mixed with HgI<SUB>2</SUB> and a mixture of Cu<SUB>2</SUB>HgI<SUB>4</SUB> and CuBr when mixed with HgBrI. CuI and HgBr<SUB>2</SUB> react differently in different molar ratios. In a 1:2 molar ratio mixture of CuI and HgBr<SUB>2</SUB>, a new product CuHgBr<SUB>3</SUB> and HgBrI are obtained. Data for lateral diffusion best fit the equation <I>X<SUP>n</SUP></I>=<I>kt</I> where <I>X</I> is the thickness of product layer at time <I>t</I>, and <I>n</I> and <I>k</I> are const. Formation of solid solutions among reactant and product phases is also noted.
