(l) At present, there are millions of kinds of organic compounds found in nature and only about 100,000 of inorganic materials. This is because carbon is bonded to carbon atoms through covalent bonding. Inorganic Compound form a long carbon chain. For example, carbon and hydrogen atoms can form many kinds of hydrocarbons such as methane, ethane, propane, and so on. This is one of the main reasons for the wide variety of organic compounds. In all kinds of natural organic matter, they are usually composed of a few elements, Inorganic Compound in addition to carbon, almost always containing hydrogen, often containing oxygen, nitrogen, and some also contain sulfur, phosphorus and so on.
(2) The heterogeneous phenomena in organic matter are very common, but inorganic materials are rare. Many organic compounds have the same chemical and molecular weight, but their physical and chemical properties often vary greatly. For example, the molecular formula of ethanol and dimethyl ether is c2h6o, Inorganic Compound the relative molecular mass is 46.07, but they are two different chemical compounds because the atoms in the molecule are arranged in different order.
The heterogeneous phenomenon is another important reason that leads to a wide variety of organic compounds.
(3) The melting point of solid organic matter is not high, generally no more than $number. 2~673.2K. In the presence of air, the vast majority of organic matter can be burned, Inorganic Compound in which carbon elements are converted into CO2, the hydrogen elements are converted into $literal, and nitrogen is converted into nitrogen.
(4) There is an obvious covalent bond property between atoms in organic molecules. Therefore, most organic matter belongs to Nonelectrolyte, it is insoluble in water and soluble in organic solvents, Inorganic Compound and the reaction between organic matter is often slow and often requires the use of catalysts.
(5) Many organic compounds have special physiological function, which is the carrier, ingredient or product in the process of life activity, such as enzymes, hormones, vitamins and so on.
Application of inorganic silicon compound refractories for the development of silicon compound cementing refractories resistant to water and acid resistance due to the complex engineering conditions, Inorganic Compound there is acid water before and after the heating of the project, Inorganic Compound or in the heat of the role of acid medium, require refractory materials have heat resistance and acid resistance to water. The unheated water glass refractory specimens immersed in different types and concentrations of acid see table in water storage than in acid storage strength decreased, than in the air curing strength also decreased.
The high-temperature performance of sodium silicate refractories, acid and water resistance and sodium silicate properties, sodium fluoride content, aggregate types, Inorganic Compound in the production should be strictly controlled. The modulus of sodium silicate is the High-temperature property of refractory. Acid and water resistance can have a significant impact, high modulus, with good acid resistance and high temperature performance modulus low will reduce these properties. Generally the choice of modulus is better.
At home and abroad, the application of inorganic silicon compounds in refractory materials has been reported, and new technologies and materials have been developed.
