The production process of pharmaceutical grade magnesium oxide is a complex and refined process involving multiple steps and strict quality control.The following is a detailed analysis of the production process of pharmaceutical grade magnesium oxide:

Raw material preparation:

Choose high-purity magnesium ore or magnesium containing compounds as raw materials.These raw materials usually require physical processing such as crushing and grinding to facilitate subsequent chemical reactions.

Chemical reaction:

According to the specific production process,react raw materials with specific chemicals.For example,in the precipitation method,a precipitant(such as sodium hydroxide,ammonia water,etc.)is added to a solution containing magnesium ions to precipitate magnesium ions and form magnesium hydroxide intermediate.

Filtration and washing:

Filter the reacted mixture to separate the magnesium hydroxide precipitate.Then wash the precipitate multiple times to remove impurities and unreacted substances.

dry:

Dry the washed magnesium hydroxide precipitate to remove any moisture.The drying process is usually carried out at specific temperatures and times to ensure the quality and stability of the product.

Calcination:

Dry magnesium hydroxide is calcined at high temperature to decompose it into magnesium oxide.The temperature and time of the calcination process need to be strictly controlled to ensure the purity and activity of the product.

Crushing and Grading:

Grind the calcined magnesium oxide to obtain the desired particle size.Then,the crushed products are screened through grading equipment to ensure that the particle size distribution of the products meets the requirements.

Quality inspection:

Conduct comprehensive quality testing on the produced pharmaceutical grade magnesium oxide,including chemical composition,physical properties,appearance,and other aspects.Only products that meet relevant standards and requirements can be recognized as pharmaceutical grade magnesium oxide.

Packaging and Storage:

Packaging qualified pharmaceutical grade magnesium oxide and storing it in a dry and cool place to prevent moisture or spoilage of the product.

Overall,the production process of pharmaceutical grade magnesium oxide involves multiple links and steps,each of which requires strict control and precise operation.Meanwhile,with the advancement of technology and the increasing awareness of environmental protection,the production methods of pharmaceutical grade magnesium oxide are constantly improving and optimizing to meet higher quality and environmental requirements.
