Antimony ore

Beryllium chemically active, isotopes of beryllium has been found that the total of eight, including beryllium 6, beryllium 7, beryllium 8, beryllium 9, beryllium 10, beryllium 11, beryllium 12, beryllium 14, wherein only beryllium 9 is stabilized, the other The isotopes are all radioactive. In nature exist in the beryl, silicon beryllium ore and gold emerald mine in the distribution of beryllium in beryl and cat eye stone. The ore-bearing ore has many transparent, beautifully colored variants that have been the most precious gemstones since ancient times. These gemstones are recorded in ancient Chinese literature, such as cat essence, or cat stone, cat eye, opal stone, which is what we call gold green jade. These strontium-containing ores are basically variants of beryl. It can be prepared by electrolytically melting ruthenium chloride or ruthenium hydroxide. It forms a dense surface oxide protective layer that is stable in air even in red heat. It can react with dilute acid and can also dissolve in strong alkali, showing both sexes. The oxides and halides of ruthenium have obvious covalent properties, the ruthenium compounds are easily decomposed in water, and ruthenium can also form polymers and covalent compounds with significant thermal stability.

The corrosion resistance of metal ruthenium to liquid metals is not strong with the general synthetic agent ethylenediaminetetraacetic acid (EDTA), which is very important in analysis. Niobium can form polymers as well as a class of covalent compounds with significant thermal stability. Beryllium alloy is used to manufacture aircraft, roentgen tube, beryllium aluminum alloy, bronze. Also used as a moderator and reflector in atomic reactors. High purity germanium is an important source of fast neutrons. This is important for the design of heat exchangers for nuclear reactors and is mainly used as a neutron moderator for nuclear reactors. Beryllium copper alloys are used to make tools that do not generate sparks, such as key moving parts of aero-engines, precision instruments, and the like.å·²Because of its light weight, high modulus of elasticity and good thermal stability, it has become a compelling aircraft and missile structural material.

Earthworms are toxic. As long as there is only one milligram of dust in the air per cubic meter, people will get acute pneumonia - silicosis. China's metallurgical industry has reduced the content of strontium in one cubic meter of air to below one hundred thousandth of a gram, which satisfactorily solved the protection problem of cockroach poisoning. Compared with sputum, scorpion compounds are more toxic, and sputum compounds form soluble gelatinous substances in animal tissues and plasma, which in turn react with hemoglobin to form a new substance that causes tissue and organogenesis. Various lesions, paralysis in the lungs and bones, can also cause cancer.

It has the strongest ability to penetrate X-rays and is known as “metal glass”. Its alloys are irreplaceable strategic metal materials in the fields of aviation, aerospace, military, electronics, nuclear energy and so on. Beryllium bronze is the most excellent elastic alloy in copper alloy. It has good thermal conductivity, electrical conductivity, heat resistance, wear resistance, corrosion resistance, non-magnetic properties, small elastic hysteresis, no spark during impact, and is widely used in national defense. Instruments, instruments, computers, automobiles, home appliances and other industries. Beryllium copper-tin alloy is used to make the spring work at high temperature, such spring still maintain good flexibility and toughness at red hot; beryllia thermocouple for high temperature heat-resistant filler.

For example: for blow molds (air nozzles, cuts, cavities) and injection molds (cores, cavities, thimbles, plastic plugs, hot runner system fittings and inserts).

Application examples: plastic mold, stamping die, rubber die, drawing die, die-casting die, etc.
