1. English name: Sodium borate 2. CAS RN: ********4 3. Free sample
4. Widely used 1. Products details: English name:Sodium borate
Chemical name: Sodium tetraborate CAS RN:********4 Physical and
chemical properties: 1.1 Molecule formula:Na2B4O7 1.2 Molecule
weight:**1.*2 1.3 Melting point: **2.5°C(for orthorhombic crystal
A)**4°C (for orthorhombic crystal B) 1.4Density: 2.*8 (A
orthorhombic crystal) (B orthorhombic crystal) 1.5 Properties: Its
hygroscopicity is extremely strong. It is dissolved in water. It
can be slowly dissolved in methanol and formed a solution of ****6%
concentration. 2. Technical indexes: Term Index Index Index Content
of sodium borate,% ?*8 ?*6 ?*5 Diboron trioxide% ?****8 ?****8
?****8 3. Uses: Sodium Borate is mainly used in the manufacturing
high quality glass, optical glass, glaze of pottery and porcelain,
glaze of enamel, detergent, bleaching agent, cleaning agents, flame
retardant, rust inhibitor and caking agent.It could be also used as
the supporter of the lubricant used in metal wiredrawing, the
stabilizer and skeleton former in refractory material, the
wraping-flux in metallurgy, the set retarder of cement and
concrete, the buffer of PH value in water system and emulsifier of
paraffin. 4. Safety description: The product is harmful. It will
harm bodys health by swallowing, breathing in, eyes contacting,
skin contacting, eye contacting will lead to irritation. Mouse
oral: LD *0=***0mg/kg; rat oral: LD *0=***0mg/kg. Wear
safety-protective glasses dust proof gauze musk, rubber gloves
during handling it. 5. Package: It is packed in woven bag, in which
should be put two strata of plastic bags, the net weight is *5kg a
bag. 6. Storage: It should be stored in a shady, ventilating and
dry storehouse. Its shelf life is one year. It can be still used if
up to standard through retest after the specified date under normal
storage condition, sodium borate is a stable crystal, and cant lead
to chemical change. If it was moistened it would react with water
and release trace heat and result in sodium borate with ten crystal
waters so that should properly take care of it, cant expose it in
moist environment or environment of very big change in temperature
and humidity, if not it will agglomerate. Therefore it is necessary
to ensure a well package. 7. Transportation: Should avoid rain
drenched, moistened, and cant take mixed transporting with strong
oxidants during transportation. * In addition: The company could
research and develop the new products according to the special
demand of our clients.
