氧化鋁粉是采用一級工業氧化鋁、氫氧化鋁外加添加劑技術，低溫轉相煅燒后，再采用先進的粉磨技術及工藝，生產出的白色活性氧化鋁微粉，其特點是粒度均勻，易于分散，化學性能穩定，高溫收縮性能適中，具有良好的燒結性能轉化率高、鈉含量低。特別適用于定型制品和耐火澆注料、可塑料、修補料、噴補料、涂抹料等不定形耐火材料，對改善耐火材料的高溫強度、提高材料的抗侵蝕性能具有很強的作用。

1、高填充性； 其粒子球形度高、粒度分布寬、可對橡膠、塑料進行高密度填充，可得到粘度低、流動性好的混合物。如添加到各種丙烯酸樹脂，聚氨酯樹脂，環氧樹脂，樹脂，硅丙乳液等樹脂的水性液體中，添加量為5
到10
，可以提高樹脂的硬度，硬度可達6-8H。

2、高導熱率；其可高密度填充，與結晶 相比，可得到熱傳導率高、散熱性好的混合物。

3、低磨損性；其外觀為球形，對混煉機、成型機及模具等設備的磨損大大降低，可延長設備的使用壽命。

目前我國氧化鋁粉的主要用途有：散熱片、散熱油脂；半導體封裝樹脂用填充劑；有機硅散熱粘結劑混合物用填充劑；陶瓷過濾器；同時氧化鋁粉還可以做各種玻璃涂層材料，寶石，精密儀器材料等等。

1、散熱片、散熱基板用填充劑（MC基板）、導熱硅脂、相變化片。

2、半導體封裝樹脂用填充劑，可制作高壓絕緣子及電纜電線，具有耐電弧、抗漏電、高溫的灼燒分解出的氣體對人畜無害，是優良的環保填料。

3、有機硅散熱粘結劑及混合物用填充劑。

4、應用于人造大理石（仿大理石）板材及瑪瑙和玉石。可做 廚具、廚柜、餐具及豪華娛樂廳和 會議廳、裝飾板材陶瓷過濾器等。

5、高鋁耐火材料、陶瓷器件、汽車用火花塞及拋光研磨等制品的原料。

6、生產高鋁質不定形耐火材料的基本材料，是增強耐火制品性能的優質填充料。

Alumina powder is introduced
Alumina powder is using industrial alumina, aluminum hydroxide plus additive technology, low temperature phase inversion after calcining, again USES the advanced grinding technology and process, produce white activated alumina powder, is characterized by particle size uniform, easy to disperse, stable chemical performance, high temperature shrinkage performance is moderate, has a good sintering performance high conversion rate, low sodium content.Particularly applicable to finalize the design product and refractory castable, plastic, repair materials, gunning materials, daub materials such as monolithic refractories, to improve the refractory material of high temperature strength, improve the erosion resistance of has a strong role.
Alumina powder characteristics
1, high filling;Its particle spherical degree is high, wide particle size distribution, high density of rubber, plastic filler, low viscosity, liquid mixture can be obtained.Added to all kinds of acrylic resin, polyurethane resin, epoxy resin, melamine resin, silicone acrylic emulsion resin, such as liquid water, adding amount of 5 to 10, can improve the hardness of the resin, hardness can reach 6 to 8 h.
2, high thermal conductivity;It can be filled with high density, compared with crystalline silicon powder, high thermal conductivity, heat dissipation good mixture can be obtained.
3, low wear and tear ";Its appearance is spherical, the mixing machine, molding machine and mold equipment wear and tear is greatly reduced, can prolong the service life of equipment.
Alumina powder use
At present, the main purpose of the alumina powder are: heat sinks, heat oil;Semiconductor packaging resin filling agent;Organic silicon thermal binder mixtures with filling agent;Ceramic filter;Alumina powder at the same time also can do all kinds of glass coating material, gem, precision instruments, etc.
1, radiator, radiator substrate with filler (MC), thermal conductivity silicone grease, phase change.
2, with semiconductor packaging resin filling agent, can produce high voltage insulator electric wire and cable, arc resistance, decomposition of the leakage resistance, high temperature burning gas harmless to human and animal, is a good environmental protection packing.
3, organic silicon thermal binder and mixture with filler.
4, applied to artificial marble, imitation marble plank and jade and agate.To do high-grade kitchen utensils and appliances, kitchen cabinets, cutlery and luxurious recreation and luxury hall, dalle ceramic filters, etc.
5, high alumina refractories, ceramic components, automotive spark plugs and polishing abrasive products, such as raw materials.
6, high aluminum monolithic refractories production of basic materials, is to enhance the performance of refractory products of high quality filling material.
