About us
We are a new brand enterprise focused on advanced high performance materials, including crystal
material, minor metals and chemicals, which is mainly used as raw material for ceramic materials,
photoelectric materials and semiconductor industry.
Materials used in semiconductor include various tellurium compound, arsenic compound,
cadmium compound, indium compound and so on. They are compound and grew under strict
condition to avoid impurity.Most of their purity is above 99.999%. Some models could be
customized according to request like calcium tellurium.
Materials used in optic is customized or grew to request mostly. We should know like size,
orientation, proportion to customize it as ITO, mercury cadmium tellurium,highpure germanium,
doped garnet and so on.
Materials used in ceramic enhance strength, great special property like chemical ceramic,
corrosion-resistance property, advanced strength, electronic ceramics.Those materials play
important role in ceramic industry.
Chemicals used in medical have part of antifungal, selenium supplement, health
protection,abirritant, antiseptic, disinfector, measuring serum, cure skin disease, contraceptive and
so on.
Special chemicals are those that are difficult to produce or rare, but inevitable in some industry. It
is our aim to find more better technology and application.
Semiconductor
Semiconductor material is a kind of electronic materials owning semiconductor properties. Its
conductivity property is between that of conductors and that of insulators. Semiconductor
materials are divided into four categories, elementary semiconductor, inorganic compound
semiconductor, organic compound semiconductor, non-crystalline and non-liquid semiconductor.
Elementary semiconductor include germanium, silicon, germanium, tellurium.
Inorganic compound semiconductor include nano metal powder, gallium arsenide, indium
phosphide, cadmium sulfide, bismuth telluride, lanthanum sulfide, scandium oxide, yttrium oxide.

Thallium metal
Thallium is soft gray metal. Using newly developed method of flame spectroscopy, thallium
produces a notable green spectral line. Thallium tends to oxidize to the +3 and +1 oxidation states
as ionic salts. The +3 state resembles that of the other elements in the thallium’s group(boron,
aluminum, gallium, indium). The +1 state, which is far more prominent in thallium than the
elements above it, recalls the chemistry of alkali metals.Thallium is refined from zinc scrap.
Approximately 60-70% of thallium production is used in the electronic industry, and the
remainder is used in the pharmaceutical industry and in glass manufacturing. It is also used in
infrared detectors.

Mercury
Mercury is a kind of fluid metal in normal temperature with fluidity. It get heaviest density in all
liquid. Many different metal could dissolve into amalgam in mercury, thallium most, its dissolve
42.8% when 18 degree Celsius, iron the least, 1.0*10-17
%, so mercury could be packed with
ironware.
Chemical property of mercury is stable, which is not easy to be oxidized and corroded. When
activated with sulfur, HgS is produced, when activated with chlorine, HgCl3 or Hg2Cl2.Standard
electric potential is +0.86, electrochemical equivalent is 7.483 gram/ampere.hour.
Mercury and the compound get many kinds of uses, like chemical, electric appliance, instrument,
medicine, metallurgy, military, new technique and so on.
In chemical industry, mercury cathode electrolyze salt solution into chlorine and caustic soda. It is
also used as substitute for water as heating medium or thermostat of higher temperature in
distillation equipment. Mercury is widely used in electric appliance and equipment, as mercurial
thermometer, gyroscope or pressure capsule for airplan or steamer sailing at night. It could be used
in production of different electric switch, mercury lamp, mercury rectifier, oscillator, mercury
battery and primary battery and so on. Mercury also could be sued as coolant and anti-radiation
material in atomic reactor. Considering mercury could be melted with various metal into amalgam,
it is used in metallurgy to extract and purify metal, as patio process in gold or other rare metals
purification. Gold or silver amalgam turn hard rapidly, which is used as dental material usually.
Main used in refining gold.after screening by water,the granule left is different size grain,even
ash.The larger granule could be picked out,but many of which is too small to pick.It could be use
mercury to recover,because the mercury could absorb gold,when don’t take in fully,it still
fluid,then cover them with cloth,forcing out the redundant mercury,Amalgam is left.Distilling the
mercury by put the amalgam in stove.The finished gold contain silver usually.Then using other
method to dispart the gold and silver.
Mercury compound also have different uses. Mercury oxide as antifouling composition could be
used as oil paint for ocean ship bottom, depolarize in dry cell. Mercury bichloride used in tanning,
photograph and so on. Mercury sulfide is a kind of red coating used in rubber and printing ink.
