Benzoyl peroxide, also known as Dibenzoyl peroxide, commonly known as Initiator BPO,It is a strong oxidant, used as a monomer polymerization initiator for polyvinyl chloride, unsaturated polyesters, polyacrylates, etc., as a crosslinking agent for polyethylene, and as a rubber vulcanizing agent.

Benzoyl peroxide is an oxidizer, which is principally used as in the production of polymers.
As a bleach, it has been used as a medication and a water disinfectant.In specialized contexts, the name may be abbreviated as BPO.
As a medication, benzoyl peroxide is mostly used to treat acne, either alone or in combination with other treatments.Some versions are sold mixed with antibiotics such as clindamycin. t is also used in dentistry for teeth whitening.
Benzoyl peroxide is also used in the plastics industry and for bleaching flour, hair, and textiles.It is also used to remove stubborn stains from dolls and other plastic toys, although some users have claimed that the product has unwanted long-term effects of discolouring the item.

First, gallium compound semiconductors are widely used in the electronics and microelectronics industries, as infrared optical and infrared detectors, microwave communication and microwave integration, integrated circuits, red, yellow, blue, green and white light-emitting diodes, GaAs solar cells are The highest conversion rate so far, the United States and Japan intend to use this to build a space power station. Civilian computers, color TVs, audio and medical equipment are also needed.
Second, gallium and indium, thallium, tin, bismuth, zinc, etc. can be composed of a series of low-fluxing alloy (see Table 2), for temperature measurement and control at 3 ℃ to 65 ℃, mercury generation instrument was given bead in the industry as Cooling circuits for supports, metal coatings, the electronics industry, and the nuclear industry. Gallium and copper , nickel , tin, gold, etc. can form a cold flux (see Table 3), suitable for difficult-to-weld shaped thin walls, cold welding and cavity blockage between metals and ceramics. Ga-Sn-In, or Ga-In as quartz thermometers temperature to 1500 deg.] C rather than mercury thermometer that will burst.

Third, other uses of gallium include: Ga-Si is a promising catalyst for automotive exhaust gas purification; in 1989 Germany, France, Italy, the former Soviet Union and the United States tried to use radioactive energy for beta transfer using GaCl 3 and neutrinos. Determination, used as underwater communication.
