片狀氧化鋁微粉對(duì)標(biāo)PWA15用于砷化鎵硅片研磨

PRODUCT/產(chǎn)品: Platelet Calcined Aluminum Oxide /片狀氧化鋁

DESCRIPTION/產(chǎn)品介紹:

Platelet calcined alumina powder, also known as tabulated aluminum oxide grinding powder. It is named after its particle crystal structure being in the shape of scales/flat plates. The crystal form of flake alumina is α- Al2O3 has high hardness and grinding performance. In the electronics industry, polishing and polishing require high surface precision. To ensure precise grinding effects and yield, abrasive materials with sharp crystal shapes can no longer meet the requirements. The surface of the abrasive particles of flake/flat alumina is flat and smooth, and the diameter-to-thickness ratio of the particles can be adjusted by adjusting the synthesis method. Grinding semiconductor chips or other microelectronic components is less prone to scratches, greatly improving the yield of qualified chips. The production of platelet calcined alumina adopts a high-temperature calcined method to promote the lateral growth of crystals and form regular hexagonal powders with a tabulated structure. The suspension-treated aluminum oxide grinding powder of platelet shape gets a uniform particle size distribution. That ensures a fine grinding surface.

片狀氧化鋁又稱為平板狀氧化鋁，因其顆粒晶型為鱗片/平板形狀而得名。片狀氧化鋁晶型為α-Al2O3，具有很高的硬度和研磨性能。在電子行業(yè)的打磨拋光對(duì)表面的精細(xì)度要求高，為保證精細(xì)的研磨效果和成品率，晶體形狀為尖角狀的磨料已經(jīng)不能滿足要求。片狀/平板狀氧化鋁的磨粒表面平整光滑，顆粒的徑厚比可以通過調(diào)整合成方法進(jìn)行調(diào)節(jié)。研磨半導(dǎo)體晶片或其他微電子元件時(shí)不易產(chǎn)生劃傷，大大提高了晶片的合格品率。片狀氧化鋁的生產(chǎn)采用高溫?zé)Y(jié)的方法，促使晶體進(jìn)行橫向生長(zhǎng)，并形成具有片狀結(jié)構(gòu)的規(guī)則六角型粉體。水洗分選工藝的片狀氧化鋁粒度集中度高，有利于研磨表面的一致性。
