Lightweight Magnesium Carbonate
技术指标
Product Description
Introduction
Lightweight magnesium carbonate is a white, loose powder with a pale appearance. It is non-toxic, odorless, and stable in air. Its relative density is 2.16. It exhibits slight solubility in water, forming a weakly alkaline aqueous solution. It is insoluble in ethanol but can be dissolved by dilute acids, causing effervescence in the process. This material is characterized by its porous structure, excellent thermal insulation properties, and low density.
