The scientist is the author of fundamental research in physics, chemistry, meteorology, metrology, economics, fundamental works on agriculture, aeronautics, public education, chemical technology and other works related to the needs of the productive forces of Russia.
In 1854-1856 he investigated the phenomenon of isomorphism, describing the relationship between the chemical composition of compounds and their crystalline form, as well as the dependence of elementary properties on the value of atomic volumes.
In 1860, a scientist discovered the critical temperature or temperature of absolute boiling of liquids.
Dmitry Mendeleev is the author of the first Russian textbook Organic Chemistry in 1861.
In 1859, he designed a device for determining the density of a liquid - a pycnometer.

D Mendeleev investigated gases and in 1874 found the general equation of state for an ideal gas.
The scientist put forward a hypothesis in 1877 about the origin of heavy metals from carbides of oil. Today it is not accepted by most scientists. D. Mendeleev proposed the principle of fractional distillation in oil refining.
In 1880 he put forward the idea of underground coal gasification.
He worked on the chemicalization of agriculture, promoted the use of mineral fertilizers, and irrigation of land.
In 1890-1892, the scientist, together with I Cheltsov, took part in the laboratory development of smokeless powder.
He is the author of a number of works on metrology, proposed the most accurate weighing techniques, developed the best design of the rocker arm and lock, created the exact theory of scales.
In some years, Dmitry Mendeleev's interest was close to mineralogy. And now his collection of minerals is carefully kept in the Museum of the Department of Mineralogy of St. Petersburg University. From his table, the rhinestone druse is the best exhibit in the quartz display case. The drawing of the Druse was placed by him in the first edition of General Chemistry in 1903.
While still a student, Dmitry Mendeleev performed work on isomorphism in minerals.
Dmitry Mendeleev's path in science began with the observation of glassmaking processes. Perhaps this fact played a decisive role in the choice, because indeed, this topic is directly related to the chemistry of silicates and naturally comes into contact with his research in one form or another.
When studying glass, Dmitry Mendeleev was able to better understand the nature of silicon compounds and on this substance he was able to discern important features of a chemical compound in general.
Dmitry Mendeleev devoted about 30 of his works to the topics of silicate chemistry, glass making, and the glassy state.
