化學(xué)的特性
white crystals or powder
使用
Tin(II) fluoride is used in the prevention of dental caries. It is an active ingredient in toothpastes.
一般的な説明
White crystalline solid. Sinks and mixes with water.
空気と水の反応
Water soluble.
反応プロフィール
Tin(II) fluoride, a strong reducing agent, is incompatible with oxidizers. Avoid contact with acids - HF fumes may be produced [USCG, 1999].
危険性
Toxic by ingestion, strong irritant to skin
and tissue.
健康ハザード
EYES: Severe irritation - corrosive, irreversible. SKIN: Corrosive on abraded skin, no effect on intact skin.
安全性プロファイル
Poison by ingestion and
intraperitoneal routes. Questionable
carcinogen. Mutation data reported. When
heated to decomposition it emits toxic
fumes of F-. See also TIN COMPOUNDS.
職業(yè)ばく露
Stannous fluoride is used in dental caries (tooth decay); as an ingredient of cavity-preventing toothpastes.
輸送方法
UN2811 Toxic solids, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required. UN2923 Corrosive solids, toxic, n.o.s., Hazard class: 8; Labels: 8-Corrosive material, 6.1Poisonous material, Technical Name Required
不和合性
A strong reducing agent. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Reacts with acids, forming hydrogen fluoride fumes. Reacts violently with chlorine and metal nitrates. Reacts with metals releasing flammable hydrogen gas.
