Light burnt magnesia powder has many uses.
In the petrochemical industry, the material of refining equipment must be insensitive to thermal expansion, cold shrinkage, good thermal conductivity, good heat resistance, and can withstand acid-alkali corrosion and salt corrosion. In view of this working environment, vigorous research is carried out to produce a neutral refractory material, which is specially used in the petrochemical industry, while in some electric industries. Furnace and metal refining industry need a kind of material which has good resistance to alkaline waste slag and iron, as well as higher resistance to high temperature than clay and silicon brick. Professional researchers have successfully manufactured an alkaline material which can meet these conditions through changing the formula of the material and numerous experiments. Some working environments are acidic. It is necessary for materials to withstand both high temperature and acid corrosion, so people devote themselves to the research and production of acid refractories.
In many special industries, more different materials are needed. For example, in the high temperature inorganic coating industry and fiber reinforced ceramic industry, special refractories are needed.
How many functions an object has, how many places it can play a role, that is to say, the more powerful its function is, the more places it can test its function value. Refractories have been deposited for thousands of years and now become a high temperature product with many functions, strong practicability and wide application. He not only plays a leading role in high temperature industries, such as steel manufacturing, boiler manufacturing, ceramic manufacturing, but also has a wide range of applications in power industry, military industry and so on.
The raw ore can be extracted, purified, processed and added with different materials to produce materials with different functions. For different industries in different production environments, refractories according to their own characteristics, produce different properties of materials to meet the needs of various industries.
Fire prevention and theft prevention has always been the focus of attention since ancient times. In ancient times, there was always a special person who repeatedly emphasized "dry days, careful candles" in the night. It can be seen that the ancient superiors paid great attention to fire prevention. Just because of the insufficient scientific development at that time, people only knew that clay and water could fire and extinguish fire. So in ancient times, there were clay figures in many buildings, small buildings must have water storage devices, large and medium-sized buildings must be equipped with pools or other artificial waters, and urban-scale buildings generally have moats. Because people in ancient times knew little about refractories, they could only do so much.
