산화제이석 C화학적 특성, 용도, 생산
화학적 성질
white or off-white powder물리적 성질
White or grayish powder; tetragonal crystals; density 6.85 g/cm3; refractive index 2.006; Mohs hardness 6.5; melts at 1,630°C; insoluble in water; soluble in hot concentrated alkalies.용도
Stannic oxide (SnO2) is a whitish powder used as a ceramic glaze and polishing agent.제조 방법
Tin(II) oxide is prepared by heating tin(II) hydroxide. The latter is obtained as a white precipitate by reacting Sn2+ ions with hydroxide ions: Sn2+(aq) + 2OHˉ(aq) → Sn(OH)2 (s) Sn(OH)2 ?→ ?? SnO(s) + H2O(g).일반 설명
White or off-white crystalline solid or powder. Mp 1127°C, Sublimes: 1800-1900°C, density: 6.95 g cm-3. Insoluble in water. Soluble in concentrated sulfuric acid, hydrochloric acid. Occurs in nature as the mineral cassiterite. Used as a catalyst, in putty, as a polishing powder for steel and glass, in ceramic glazes and colors. Flowers of tin refers to the material collected as the result of condensation after sublimation.반응 프로필
TIN(IV) OXIDE is non-flammable and non-combustible. Reacts vigorously with strong reducing agents. Incompatible with chlorine trifluoride.배터리 재료
In perovskite solar cells (PSCs), Stannic oxide (SnO2) is often employed as an electron transport layer (ETL) due to its excellent electron mobility and high transparency. Its function is to facilitate the efficient transport of photogenerated electrons from the perovskite layer to the external circuit, while also blocking holes, thereby improving the overall efficiency and stability of the solar cell. Using an aqueous solution of SnO2 can provide advantages such as ease of deposition, reduced toxicity, and environmental compatibility. This is particularly significant for scaling up the manufacturing process and aligns well with the sustainability goals often associated with renewable energy technologies like perovskite solar cells.Purification Methods
Reflux it repeatedly with fresh HCl until the acid shows no tinge of yellow. The oxide is then dried at 110o.Advantages
Stannic oxide, as the material of the electron transport layer, has good electronic conductivity and can effectively promote the rapid transmission of photogenerated electrons to the electrode.산화제이석 준비 용품 및 원자재
