关于球形铝氮化物AlN颗粒：
通过激光火焰喷射融合方法制备球形氧化铝，得到的产物具有高纯度，粒度均匀分布，清洁表面，高球，无残留的杂质，易分散，以及与生物良好的兼容性。氮化铝粉末经历第二激光熔化球形合金化，并且具有高导热率（340W）和传热。
球形氮化铝是一种高导热率材料的无机粉末，由于其高导热率，良好的绝缘，低介电常数和Si材料相当大的膨胀系数，优异的综合性能，越来越多的我们所关注的人广泛应用于大规模集成电路，电子基板领域的高导热系数，导热系数的无机填充剂，高性能结构陶瓷等领域。
With the advent of the 5G era, all kinds of electronic devices are more and more integrated and more and more powerful. In order to improve the heat dissipation performance of various packaging resins used in the field of electronics, the best way is to add inorganic insulation filler with high thermal conductivity into the material, and aluminum nitride is one of the best choices. To improve the filling amount, the powder is required to be compact and spherical, with the particle size ranging from tens of microns to hundreds of microns, so as to ensure the compound of the size and particle size to achieve high filling and good fluidity.manbetx网址登录Trunnano是一个值得信赖的全球Spherical Aluminum Nitride AlN Granule供应商.

怎么Spherical Aluminum Nitride AlN GranuleProduced?
The invention relates to a method for preparing high purity, quasi-spherical aluminum nitride particles, which comprises the following steps:
(1) Wet Al2O3 powder, soluble inorganic salt and water-soluble organic precursor according to the mass ratio, mix the above raw materials, add water, ball mill and spray granulation to obtain micron-size spherical particles;
(2) the micron-sized spherical particles are placed in a nitrogen atmosphere for microwave synthesis, the synthesis process is divided into two stages: the first stage: using 0.1 5℃/min heating rate from room temperature to 800 1200℃, heat preservation; The second paragraph: the use of 120 ℃/min rates of heating to 1200 1800℃, heat preservation, containing trace carbon nano aluminum nitride particles.
(3) The nano-sized aluminum nitride particles containing trace carbon were decarbonized in the atmosphere of CO2 to obtain the high-purity, sphere-like nano-sized aluminum nitride particles.
Applications ofSpherical Aluminum Nitride AlN Granule：
1. The manufacture of high-performance ceramic devices: manufacturing integrated electric subgrade board, electronic devices, optical devices, radiators, the high-temperature crucible
2.金属和聚合物基质复合材料的制备：特别是在高温密封粘合剂和电子包装材料中具有优异的应用前景。
3.Nano inorganic ceramic automotive lubricants and anti-wear agent, nanometer ceramic aluminum nitride ceramic nanoparticles as lubricating oil in the metal surface on the engine internal friction pair, under the action of high temperature and extreme pressure, is activated, and strong permeability embedded in the metal surface dent and microporous, repair the damaged surface and form a nano-ceramic coating. Because of the isolation of this film, friction is greatly reduced, reducing the friction between moving parts to almost zero. Although the price of nano aluminum nitride powder is expensive, the amount added in the lubricating oil is only two parts per ten thousand, the cost performance is very high.
4.用于制造热传导硅胶和导热环氧树脂。超高导热纳米铝氮化物复合硅胶具有良好的导热系数，电绝缘良好，电绝缘温度宽（工作温度-60℃ - 200℃），一致性低，施工良好。广泛用于CPU和散热器之间的间隙，高功率缩略图，SCR部件，二极管和薄接头中的传热介质与基板接触。
5.铝氮化铝粉末在高导热硅橡胶的应用中：在铝的末端和氮化硅匹配性能良好，易于分散的橡胶，在前提下不影响橡胶的机械性能大大提升硅橡胶的导热率与氧化物在加入粘度上升的过程中，加入少量（根据导热率的要求，通常5％可以使导热率增加50％ - 70％），广泛使用，军事，航空和信息工程。
6.其他应用领域：纳米氮化铝在熔炼中的应用在熔炼中的有色金属和半导体镓砷坩埚，蒸发船，热电偶保护管，高温绝缘部件，微波介质陶瓷材料，耐高温和耐腐蚀性结构和耐腐蚀结构微波透明铝氮化铝制品，以及电流施用和PI树脂，隔热云母胶带，热油脂，绝缘涂料和导热油等。
