Belong to cubic crystal system, stable in air, can be decomposed by strong acid. Density 4. 24, melting point 1473 ℃, boiling point 2489 ℃. Conversion to strontium oxide at> 1000 °c in air. Last Update：2022-01-01 11:01:33 Strontium fluoride - Preparation Method Open Data Verified Data strontium carbonate was slurried with water and reacted by gradually adding 40% hydrofluoric acid to control the mid-point pH and kept constant. The product is filtered, dried, and pulverized, and is the final strontium fluoride product. Last Update：2022-01-01 11:01:34 Strontium fluoride - Introduction Soluble in hydrochloric acid, insoluble in hydrofluoric acid, ethanol and acetone. The product belongs to the cubic crystal system, which is stable in the air and can be decomposed by strong acids. Last Update：2022-10-16 17:28:45 Strontium fluoride - Use Open Data Verified Data It can be used for manufacturing optical glass and single crystal for laser. It can also be used in the pharmaceutical industry and daily chemical industry, such as anti-caries additives for toothpaste, flux, etc. Last Update：2022-01-01 11:01:34 Strontium fluoride - Safety Open Data Verified Data plastic woven bags are lined with plastic bags, each with a net weight of 25kg, or with a net weight of 1000kg per container. It should be stored in a ventilated and dry warehouse, and should not be mixed with acids. Handling should be light and light, to prevent packaging damage. It is an inorganic toxic substance with risk code number GB 6.1 class 61513. Wash with water when touching the skin. Flush with warm water when invading into the eye. Ingestion poisoning with 2% calcium chloride gastric lavage, intravenous injection of calcium gluconate. During operation, wear work clothes, protective masks and latex gloves to prevent inhalation of aluminum fluoride dust. Production equipment should be closed and the workshop should be well ventilated. The protection of hydrofluoric acid in the process of making acid is shown in hydrofluoric acid; The protection of strontium fluoride can also be referred to barium fluoride.
