Claim:
1. A method of preparing beta-silicon carbide (β-SiC) powder comprising: forming a mixture by mixing a silicon (Si) source, a carbon (C) source, and a silicon carbide (SiC) seed; and reacting the mixture, wherein a mole ratio or carbon (C) constituting the carbon (C) source to silicon (Si) constituting the silicon (Si) source is in a range of about 1:1.8 to about 1:2.7, wherein a mole ratio between silicon carbide (SiC) and a sum of the silicon carbide (SiC) and the silicon (Si) source is in a range of about 0.01:1 to about 0.2:1, and wherein the beta-silicon carbide (β-SiC) powder has a purity in a range of 99.999% to 99.99999999%.
