Dysprosium oxide is a chemical substance with the chemical formula Dy₂O₃. White powder, slightly hygroscopic, easily absorbs carbon dioxide when exposed to the air and turns into dysprosium carbonate. Magnetism is many times stronger than high iron oxide.

Silicon nitride powder is an inorganic substance with the chemical formula Si3N4. It is an important structural ceramic material with high hardness, inherent lubricity, and wear resistance.

What color is oxidized? Oxidation is an inorganic compound that is insoluble in water. Its molecular formula is PR6O11. It has a cubic fluorite structure and is the most stable oxidation at room temperature and normal pressure. Oxidation is a black powde

Germanium disulfide is an inorganic compound whose chemical formula is GeS₂. Germanium disulfide is a semiconductor material.

Ytterbium oxide, also called ytterbium trioxide, has the chemical formula Yb2O3. The pure product is a white powder, and it is yellowish-brown when it contains a small amount of thorium oxide. Insoluble in water and cold acid, soluble in warm dilute acid.

Tungsten carbide is a gray powder with metallic luster. It is insoluble in water, hydrochloric acid and sulfuric acid, but easily soluble in a mixed acid of nitric acid and hydrofluoric acid.

Heating metal gallium in the air to oxidize it or calcining gallium nitrate at 200-250°C, gallium hydroxide and some gallium compounds can form Ga2O3. Ga2O3 has five isomers: α, β, γ, δ, ε, of which the most stable is β-isomer. When heated to above 1000℃

Graphene is a new material with a single-layer sheet structure composed of carbon atoms. It is lighter than air and stronger than steel. With its excellent conductivity, light transmittance and toughness, it will play a very large application potential in
