到目前为止，所报道的h-BN的状态方程彼此相差很大。讨论了产生这种差异的原因，并提出了能再现0.5GPa范围内所有P-V-T数据的状态方程。 提出的状态方程为P=（3/2）K 0 {（V0/V）7/3−（V0/V）5/3}[1−（3/4）（4− K 0 ′）{（V0/V）2/3−1}]+{α 0 K 0+（K/T）Vln（V0/V）}（T-T0），其中K 0 = 25 GPa，α 0 K 0 = 1.1 × 10-3GPa/K，（K/T）V= 5.0 × 10−3GPa/K。
The equations of state of h-BN reported so far differ considerably one another. The reasons for the discrepancy are reviewed and the equation of state that can reproduce all the availableP–V–Tdata within about 0.5 GPa is proposed. The proposed equation of state is P=(3/2)K0{(V0/V)7/3−(V0/V)5/3}[1−(3/4)(4−K0′){(V0/V)2/3−1}]+{α0K0+(∂K/∂T)Vln(V0/V)}(T−T0), whereK0= 25 GPa,,α0K0= 1.1 × 10–3GPa/K, and (∂K/∂T)V= 5.0 × 10−3GPa/K.
