Claims25
An alkoxymagnesium particle, comprising a reaction product of a reaction mixture comprising reactants of 1) magnesium powder;
- 2) a mixed alcohol;
- 3) a halogenating agent;
- 4) a titanate compound;
- and optionally 5) a dispersing agent, wherein the alkoxymagnesium particle comprises titanium in an interior and on a surface thereof, the bulk density units should be changed from g/m3 to g/cm3
- wherein a mass percentage of the titanate compound is 0.1-8.0 wt % of a total weight of the alkoxymagnesium particle, and
- wherein the dispersing agent is selected from hexane, heptane, octane, decane, benzene, toluene, xylene, and mixtures thereof.
An alkoxymagnesium particle, comprising a titanate compound in the particle, wherein the titanate compound is distributed from an interior and to a surface of the alkoxymagnesium particle and has a bulk density in a range of 0.40 g/cm3 to 0.47 g/cm3, and a mass percentage of the titanate compound is 0.1-8.0 wt % of a total weight of the alkoxymagnesium particle.
