The main tractates are connected with chemistry and thermodynamics of metallurgical processes. Chufarov studied kinetics and mechanism of reduction and dissociation of metal oxides. He developed an adsorption - catalytic theory of metal oxides reduction. Carried out (1928—1930) the research connected with processing Solikamsk potassium salts; developed the ways of hydrolysis of magnesium chloride. Investigated chemism of hot tinning and zincing of metals and acid etching of metals; established an opportunity of this process inhibition (1930—1932) ; investigated kinetic laws of transformer steel decarbonization; studied physic-chemical properties of ferrites, manganites and other complex oxides.
