• Sample service: samples available for customer testing and evaluation
• After‑sales support: dedicated contact person; quality issues handled per agreement with fast technical response

• Raw material pretreatment: select magnesite / dolomite / brine, remove gravel impurities and complete purification
• Calcination decomposition: segmented temperature‑controlled calcination to thermally decompose magnesium feedstock into magnesium oxide
• Crushing & classification: cooling, coarse crushing, airflow ultrafine crushing and air‑separation for different particle grades
• Purification: multi‑stage water washing for impurity removal, drying, adjustment of activity and bulk density
• Inspection & packing: full‑item test for finished goods, moisture‑proof sealed packing and warehousing with traceable batches

• Protection: Wear dust mask, gloves and work clothes. Avoid dust inhalation and direct skin contact. Closed feeding equipment is preferred.
• Dry mixing: Fully mix dry raw materials before adding solvent to minimize agglomeration.
• Wet feeding: Add powder slowly in batches with continuous stirring for slurry preparation or neutralization reaction to ensure sufficient reaction.
• Handling: Avoid package damage during transportation to reduce dust emission.

• Storage: Store in cool, dry and ventilated warehouse. Keep tightly sealed away from air to prevent moisture absorption, carbonization and caking.
• Dust: Powder dust may irritate respiratory tract. Keep workplace well‑ventilated. Keep away from open flame.
• Contact: Rinse eyes with plenty of clean water; wash skin after contact. Seek medical help in case of accidental ingestion.
• Compatibility: Avoid bulk storage together with strong acid. Do not mix different grades of magnesium oxide.
• Use up promptly after opening; reseal leftover materials.
