    摘要: To provide a transition metal-containing hydroxide, which is a precursor of a lithium-containing composite oxide, with which it is possible to obtain a lithium ion secondary battery excellent in the discharge capacity and cycle characteristics, by using as a cathode active material a lithium-containing composite oxide obtained from the hydroxide. A transition metal-containing hydroxide, which is a precursor of a lithium-containing composite oxide, wherein in a distribution of the logarithmic derivative pore specific surface area relative to the pore size, obtained by BJH method, the proportion of the sum of the logarithmic derivative pore specific surface areas with pore sizes of 10 nm or larger, to 100% of the sum of the logarithmic derivative pore specific surface areas in the entire distribution, is at least 23%.

    摘要: A glass substrate for a mask blank includes a rectangular-shaped main surface on which a film having a circuit pattern is to be formed. The main surface includes a quadrangular peripheral frame and a square-shaped center area defined by excluding the frame. The center area has a longitudinal length of 142 mm and a lateral length of 142 mm. A surface morphology of the center area is expressed by the following formulas. A flatness of a sum of compositing all of aklPk(x)Pl(y) is less than or equal to 20 nm when a sum of k and l is greater than or equal to 3 and less than or equal to 9. The flatness is less than or equal to 20 nm when a sum of k and l is greater than or equal to 10 and less than or equal to 30. { z ⁡ ( x , y ) = ∑ k = 0 N 1 ⁢ ⁢ ∑ l = 0 N 2 ⁢ ⁢ a kl ⁢ P k ⁡ ( x ) ⁢ P l ⁡ ( y ) P k ⁡ ( x ) = 1 2 k ⁢ k ! ⁢ d k dx k ⁡ [ ( x 2 - 1 ) k ] P l ⁡ ( y ) = 1 2 i ⁢ l ! ⁢ d l dy l ⁡ [ ( y 2 - 1 ) l ]

    摘要: A glass article includes a glass plate including a rugged surface configured to diffuse and reflect an external light formed on at least one of main surfaces; and a functional film formed on the rugged surface. A transmission haze of the glass article is 28% or less. On a surface of the functional film opposite to the glass plate, within a region with a visual field area of 60000 μm2 observed by using a laser microscope, a pore representative diameter is less than 12 μm. An area ratio of a surface area A (μm2) of the surface of the functional film within the region to the visual field area (A/60000) is 1.02 or more and 1.07 or less.
