One-step synthesis of basic magnesium sulfate whiskers by atmospheric pressure reflux

- 5Mg(OH)2·MgSO4·3H2O (513MOS) whiskers were synthesized by an atmospheric pressure reflux method.
- Long reaction time and high MgSO4 concentration were necessary under gentle reaction conditions.
- The growth of 513MOS whiskers is a relatively slow liquid phase deposition process.
- Porous MgO whiskers were derived via 1,020 °C calcination from 513MOS whiskers.
