We are offering 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.

We are offering gallium nitride. Gallium nitride is little yellow or gray powder, which is stable in chemical property, don’t dissolve in water, don’t react with water, dense inorganic acid, little react with faint acid, slowly react with alkali liquor. When heat to 800 celsius, it would be oxidized and get gallium oxide. Gallium nitride is regular rhombohedron, hexagonal crystal system lead-zinc ore structure. It is direct gap semiconductor. Band gap under room temperature is 3.39ev.
