摘要
采用氯化铵-硼砂法合成的h-BN,得到含量97%,粒度小于1微米的h-BN,G.I.值为3.4左右,以反复试验,温度为900℃最佳。高温精制温度为2060℃,粒度为3～5μm,G.I.值为1.72,纯度在99%以上。
Hexagonal boron nitride （ h - BN） was synthesized using ammonium chloride and borax as raw materials. The product content of the h - BN was 97%. The particle size was less than 1 μm and the GI value was 3. 4. Through numerous tests, it can be found that the best reaction temperature is 900 ℃. Under 2 060 ℃ refining temperature, h - BN product with 3 μm - 5 μm particle size , 1.72 GI value, and 99% purity can be obtained.
