Magnesium oxide ceramics is the performance of dependent on magnesium oxide, magnesium oxide as Magnesium Oxide price an important additive, the selection of magnesium oxide ceramic products will not be too different, magnesium oxide added to the magnesium oxide ceramics, will make the sintering performance of magnesium oxide ceramics and thermal shock resistance to be more obviously improved. Magnesium oxide was added to the magnesium oxide ceramic, which significantly improved the sintering density and thermal shock resistance of the specimen, and greatly promoted the sintering of magnesium oxide ceramic. Magnesium oxide as an inorganic substance, high stability, low volatility at high temperature, can activate the lattice, promote sintering, is an effective class of additives, magnesium oxide to improve the sintering performance of magnesium materials. Magnesium oxide ceramics generally caustic calcined magnesite use hot pressing sintering and hot isostatic pressing sintering. Hot pressing sintering facilitates full contact with the fine powder, thereby reducing the sintering temperature of magnesium oxide ceramics and shortening the sintering time.
The acid-base neutralization characteristics of magnesium oxide can be applied to the restoration of ancient books and the protection of archives, the restoration work of ancient books is a complex and cumbersome process, the use of magnesium oxide needs to be carefully selected, magnesium oxide has the characteristics of acid-base neutralization, the alkalinity of magnesium oxide can absorb acidic substances in ancient books and archives, so that the acidic substances are detached, so as to achieve the role of restoration. The selection of magnesium oxide products needs to pay attention to its impurities, fineness, especially physical indicators, etc., products with high impurity content will bring secondary harm to ancient books and archives. The choice of fineness is to look at the number of meshes and the Magnesium Oxide MgO second is to look at the particle size distribution, and the more uniform the particle size distribution, the more stable the product application. The raw materials for the manufacture of ancient books and archives are wood products, and with the continuation of time, the paper is easily acidified, which is easy to mildew, and this loss is irreversible, magnesium oxide is weakly alkaline in water, can neutralize acidic substances, and the particle size of magnesium oxide is very fine and easier to penetrate into the fiber, which can protect the paper.
