Calcium carbonate has a wide range of uses because of its properties

Calcium Carbonate has a wide range of uses because of its properties. A defining substance house of CaCO₃ is its thermal behavior. When heated to approximately 825°C, it decomposes into Calcium Oxide( CaO) and Carbon Dioxide( CO₂). 

This reaction is fundamental to the production of lime (quicklime) for industrial use. Industrial Uses The utility of Calcium Carbonate spans multiple sectors, primarily categorized into "Ground Calcium Carbonate"( GCC) derived mechanically from natural rock and "Precipitated Calcium Carbonate" (PCC) synthesized via chemical reaction. 1. Construction and Infrastructure As the main element of limestone and stone, CaCO₃ is the core of the construction industry. 

It is used immediately as a tower stone and as a key raw material for cement production and street particles. Its high brightness and hardness even make it ideal for bitumen fillers. 

2. Plastics and Plastics In the plastics industry, particularly for Polyvinyl Chloride( PVC), Polypropylene( PP), and Polyethylene( PE), CaCO₃ acts as a functional filler. It enhances the rigidity, impact resistance, and thermal balance of the final item while significantly reducing manufacturing costs by displacing more costly resins. 

3. Paper and Paint The compound is prized for its high brightness (typically >90%) and opacity. In the papers business, it is used to coat and complete document, creating a smoother, brighter, and more printed surface. In paints and coatings, it serves as a steady, weather-resistant extension that improves protection and longevity. 

4. Advanced Energy Technologies Recent advances have pushed CaCO₃ into high-tech areas. Research indicates its use as a forerunner for mica levels in solar cells, enhancing balance. Moreover, it is utilized in the natural production of permeable carbon materials for Lithium-ion batteries, acting as a pattern and catalyst to enhance energy safe-keeping performance. 

5. Food, Pharma, and Healthcare Due to its high concentration of elemental calcium( 40%), it is widely used as a dietary calcium supplement and an antacid to neutralize stomach acid. In pharmaceuticals, it acts as an inert filler for tablets, while in food, it serves as an anti-caking agent and white pigment( Food Additive E170).

Matrine  Sophora flavescens Chemical composition As early as the early 1930s, the Soviet Union began to study it abroad, and China began in 1972. The focus of research at home and abroad is on alkaloids. The alkaloids extracted, separated and identified from Sophora flavescens plants in China mainly include oxymatrine (C15H24N2O2), matrine (C15H24N2O), isomatrine (Iosmatrine, C15H24N2O), hydroxymatrine (sophor-anol), sophocarpine (C15H22N2O), N-oxysophocarpine (C15H22N2O2), sophoramine, sophoridine (Sophoridine, C15H24N2O), Aloperine, sparteine, N-methylcytisine, anagyrine, bap-iifoline, sophocarpine, d-matrine, d-isomatrine, d-oxymatrine, l-anagyrine, l-methyleytisine, l-baptifoline, kurarid-in, sophoranol (C15H24N2O2), sophoranhol N-oxide (C15H24N2O3), N-methylcytisine (C12H16N2O), and other alkaloids. Flavonoids: The flavonoids contained in Sophora flavescens are mostly dihydroflavones and dihydroflavonols, and there are also flavones, isoflavones, chalcones, etc. The flavonoids...
