Abstract	MgO is an important inorganic material, which can be used in many aspects, such as catalyst, toxic-waste remediation agent, adsorbent, and others. In order to make use of MgO, nano-MgO was prepared by ultrasonic method using Mg (CH3COO)2.2H2O as precursor, NaOH aqueous solution as precipitant in this paper. Effect factors on MgO nano-particle size were investigated. Characteristics of samples were measured by TGA, XRD, TEM, and others techniques. The results showed that the size of nano-MgO about 4 nm could be obtained under the following conditions (ultrasonic time 20 min, ultrasonic power 250 W, titration rate of NaOH 0.25 mL/min, NaOH concentration 0.48 mol/L, calcinations temperature 410 °C, calcination time 1.5 h, heating rate of calcination 5 °C/min). It was a very simple and effective method to prepare nano-MgO. Keyword: MgO; nano-particle size; ultrasonic method. MgO is an exceptionally important material, which used in catalyst, toxic-waste remediation agent, or as an additive in refractory, paint as well as for fundamental and application studies [23]. Ultra-fine metal oxide particles can be used as bactericide, adsorbent, and catalyst. MgO in particular has shown great promising application as a destructive adsorbent for toxic chemical agent [24]. This paper presented an ultrasonic route for preparing MgO nano-particles. Effect factors on MgO nano-particle size were investigated. It is a good method to prepare nano-MgO. Experimental details
