13776-74-4 - Introduction
magnesium silicate (magnesium silicate) is an inorganic compound with the chemical formula mgsio3. It is usually a white powder with the following properties:
1. Strong thermal stability: magnesium silicate is not easy to decompose or dissolve at high temperature.
2. Chemical stability: It has good resistance to acid and alkali, and is not easy to be eroded.
3. Low density: The density of magnesium silicate is low, usually 2.8-3.0g/cm³.
Magnesium silicate has many uses, including but not limited to the following:
1. Food industry: as a food additive, used as an anti-caking agent and hygroscopic agent.
2. Pharmaceutical field: Often used as drug diluent and flow agent.
3. Cosmetics: used as hygroscopic agent and regulator in cosmetics.
4. Chemical Industry: can be used as fire retardant, plasticizer and coating additives.
There are many methods for preparing magnesium silicate, mainly including the following:
1. Chemical reaction: Precipitation is generated by reacting silicate and magnesium salt solutions.
2. Solvothermal reaction: the magnesium salt and silicate are reacted by heating in an appropriate solvent.
3. Hydrothermal synthesis: under high temperature and high pressure conditions, the appropriate silicate and magnesium salt react to generate magnesium silicate.
Regarding the safety information of magnesium silicate, it is considered harmless under normal circumstances, but the following matters still need to be paid attention:
1. Avoid inhaling dust: Avoid inhaling magnesium silicate dust, because prolonged exposure may cause irritation to the respiratory tract.
2. Avoid skin contact: Avoid direct contact with magnesium silicate on the skin, so as not to cause allergies or irritation.
3. Pay attention to storage conditions: magnesium silicate should be stored in a dry, well-ventilated place, away from fire and oxidant.
