Title:
Alumina slurry, a manufacturing method for the same, and Coating liquid
Document Type and Number:
Japanese Patent JP6067016
Kind Code:
B2
Abstract:
Disclosed is an alumina slurry substantially including alpha-alumina particles and water, wherein
the alpha-alumina particles satisfy all particle diameter distribution conditions (a) to (d) mentioned below,
the alpha-alumina particles have an alumina purity of 90% by weight or more,
the content of alumina in the slurry is 20% by weight or more and 50% by weight or less, and
the slurry has a viscosity of 0.5 Pa·s or more and 15 Pa·s or less:
condition (a): the average particle diameter is 1 µm or less,
condition (b): particles having a particle diameter of less than 0.2 µm account for 7% by weight or less,
condition (c): particles having a particle diameter of more than 1.5 µm account for 15% by weight or less, and
condition (d): one or more frequency maximums exist in a particle diameter range of 0.1 µm or more and less than 0.5 µm.
