平板状氧化铝微粉对标Microgrit WCA15

PRODUCT/产品: Platelet Calcined Aluminum Oxide /片状氧化铝

DESCRIPTION/产品介绍:

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.

片状氧化铝又称为平板状氧化铝,因其颗粒晶型为鳞片/平板形状而得名。片状氧化铝晶型为α-Al2O3,具有很高的硬度和研磨性能。在电子行业的打磨抛光对表面的精细度要求高,为保证精细的研磨效果和成品率,晶体形状为尖角状的磨料已经不能满足要求。片状/平板状氧化铝的磨粒表面平整光滑,颗粒的径厚比可以通过调整合成方法进行调节。研磨半导体晶片或其他微电子元件时不易产生划伤,大大提高了晶片的合格品率。片状氧化铝的生产采用高温烧结的方法,促使晶体进行横向生长,并形成具有片状结构的规则六角型粉体。水洗分选工艺的片状氧化铝粒度集中度高,有利于研磨表面的一致性。
