Cadmium is a toxic element and its compounds are more toxic. It was meant to be a compound that didn't interact with human life, but the industrial revolution unleashed that demon. Some foreign studies have estimated that 22,000 tons of cadmium enters the soil every year. Cadmium compounds have different toxicity in nature. Cadmium sulphide and cadmium selenesulfonic acid were less toxic, cadmium oxide, cadmium chloride and cadmium sulfate were more toxic. The average dose of cadmium poisoning is 100mg.
Levothyroxine is used to treat hypothyroidism, when the thyroid gland does not produce enough thyroid hormone. It can also be used in surgery and radioactive iodine therapy to treat thyroid cancer. Levothyroxine is a class of drugs called hormones. Its job is to replace thyroid hormones normally produced by the body.
The copper nitrate character is Dark blue granular crystals. The density is 2.23g/cm3. Melting point 114.5 C. It is soluble in water and ethanol, and the water solution is acidic. Soluble in concentrated ammonia water, forming copper tetramine dinitrate complex, heating explosion occurs. Easy to absorb moisture, toxic! It is a strong oxidant. Paper immersed in copper nitrate ethanol solution can spontaneously ignite dry scrap paper. When heated to 114.5 C, it decomposes and escapes nitric acid to form insoluble alkaline salts.
Metallurgical coke powder is the coke from high temperature coking used in blast furnace smelting, casting and gasification. The recovered and purified coke oven gas produced in the coking process is not only the fuel with high calorific value, but also an important industrial raw material for organic synthesis. Metallurgical coke is a general term for blast furnace coke, foundry coke, ferroalloy coke and nonferrous metal metallurgical coke.
Fullerene C60-999 is an allotrope of carbon. Fullerene is the third allotrope of carbon discovered after graphite and diamond. Any substance consisting of an element called carbon in a spherical, elliptical, or tubular form may be called a fullerene.
Tin powder for green powder, the melting temperature of 231.88 ℃. The boiling point of 2270 ℃. Relative density 7.28. It is used as high purity reagent for electronic industry. Mainly used in the manufacture of solder paste, carbon products, friction materials, oil bearing and powder metallurgy structural materials.
Metallic stainless steel powder made of stainless steel alloy. The particles were regular spheres with a density of 7.9g/cm3 and average particle size <33 m. With good corrosion resistance and durability, the ball particles can be positioned on the surface of the film in parallel and distributed throughout the film, forming a shielding layer with excellent hiding power to block the moisture. Can also be used for sandblasting machine to process some of the higher accuracy of the workpiece.
Platinum carbon catalyst belongs to noble metal catalyst with black powder appearance and molecular weight of 195.08. Platinum carbon catalyst is a kind of carrier catalyst which supports platinum onto activated carbon. Can be used in pharmaceutical, electronic and other fields, the application is more extensive.
Rhodium wire, is thin wire metal rhodium processing material, is a good high temperature thermocouple material.
