Reagent-grade magnesium oxide is a major selling point of Xingtai Magnesium Xi Environmental Protection Materials Co., Ltd., which has very strict requirements for content, clarity, trace elements, and hydrochloric acid insolubles. Unqualified magnesium oxide indicators may directly lead to inaccurate or even incorrect laboratory data.
The so-called reagent-grade magnesium oxide is mainly used for chemical analysis reagents, but also for adhesives, electronics, phosphors, ceramics, aerospace materials and high-tech fields. General reagent grade magnesium oxide is more than 5ml / g of light magnesium oxide, the relative molecular mass of 40.30, the production method is generally used soda ash method and pure ammonium method two. Mainly the physical and chemical indicators are stable, and the impurities and metal ions are low, such as: iron ions, arsenic, potassium, sodium ions, etc., whiteness, clarity. The raw materials selected mainly take into account the difficulty of impurity removal, production costs, and the feasibility of the process flow. Considering the above factors, brine is generally used as a magnesium source, because brine is relatively easy to purify, and it is easy to control production conditions and product performance.
Reagent-grade magnesium oxide crystals are used for various substrates for thin film formation, protective film materials for PDP, optical materials, high-temperature materials, and window materials.
Reagent grade high purity magnesium oxide powder is used for PDP protective film materials, PDP fluorescent powder pastes, high purity ceramic materials, glass materials, coating materials, electronic insulation materials, various additives.
