Light burned magnesium powder It is a small artificial block for building. It is also called light burned magnesia fired brick. Solid clay refractory brick is one of the oldest building materials in the world. From the Mausoleum of the First Qin Emperor in Shaanxi to the Great Wall of Ming and Qing Dynasties in Beijing, it has inherited thousands of years of architectural civilization of the Chinese nation. So far, it is still the construction material loved by Chinese people. Clay refractory bricks are made of local materials, cheap, durable, fire prevention, heat insulation, sound insulation, moisture absorption and other advantages, and are widely used in civil construction projects.

However, the mass production of fireclay bricks has caused damage to the cultivated area in China. The per capita arable land resource in China is less than 40% of the world average level, but 700000 mu of fertile land will be destroyed in a year due to the construction of houses and firebricks in urban and rural areas. This is a warning issued by the "Seminar on New Wall Materials in 12 Southern Provinces and Cities" held in Nanchang in 2004. In China, wall materials account for about 70% of the building materials, of which clay refractory bricks still occupy a leading position in the wall materials. The clay resources required for the production of solid clay refractory bricks are more high-quality clay in arable land, so its damage to land resources can be seen.
In order to change this traditional firing method, which seriously wastes land resources, as early as 12 years ago, the "Opinions on the Development and Promotion of New Wall Materials" jointly issued by the former National Building Materials Bureau and other departments were approved and forwarded, and the "Time Schedule for Prohibiting the Use of Solid Clay Firebricks" was proposed for 170 large and medium-sized cities across the country. Shaanxi refractory industry closely follows the national policy guidance, makes effective adjustments to the production of clay refractory bricks by refractory enterprises, makes efforts to innovate, uses environment-friendly materials to replace clay, and strives to achieve the same result in use value as clay bricks.
Downstream demand decreases The growth rate of demand for fireclay bricks decreases. The downstream demand is also affected by the national macro-control. The growth rate of the national refractory output slows down, and the new capacity of the steel and cement industries decreases, which makes the growth rate of the demand for refractory decline.
Therefore, from the perspective of the current policy situation and the industry environment, the structural adjustment of the supply side of light burned magnesia powder has become the focus of the future development of steel, cement, glass and other industries. The national macro-control efforts are deepening and strengthening, so it is impossible for these industries to see explosive growth in new capacity in the near future
