There are provided an aqueous solution for separation of a dark ceramics sintered body, which can easily collect in a recyclable condition a glass from a glass with a dark ceramics sintered body, and a separating method therefor, and an aqueous solution for separation with which a dark ceramics sintered body, a conductive ceramics sintered body and a glass are separately collected from a glass with a dark ceramics sintered body formed with the dark ceramics sintered body and the conductive ceramics sintered body, and a separating method therefor. A treatment liquid (hydrofluoric acid, a mixture of ammonium fluoride and an acid, etc.) having an etching ability for at least one of a glass and a dark ceramic sintered body is prepared as an aqueous solutionfor separation of the dark ceramics sintered body, then type A treatment liquid is charged in a container, and a glass with a dark ceramics sintered bodyis placed in the container

Separating method for dark ceramics sintered body

There are provided an aqueous solution for separation of a conductive ceramics sintered body in which a conductive ceramic sintered body separated form a glass can be collected in a recyclable condition, and a separating method therefor, and an aqueous solution for separation with which a dark ceramics sintered body, a conductive ceramics sintered body and a glass are separately collected from a glass with a dark ceramics sintered body in which a conductive ceramics sintered body is formed on the dark ceramics sintered body, and a separating method therefor. A treatment liquid having an etching ability for at least one of a glass and a conductive ceramic sintered body is prepared as an aqueous solutionfor separation of the conductive ceramics sintered body, then the aqueous solutionfor separation is filled in a container, and a glass with a conductive ceramics sintered bodyis immersed into the aqueous solutionfor separation in the container

Separating method for conductive ceramics sintered body

There are provided an interlayer film separation solution and an interlayer film separation method capable of separating an interlayer film and a glass for a short period of time and collecting the separated interlayer film in a recyclable condition. An interlayer film separation solutionhaving etching ability for a glass is introduced into a container, and the introduced interlayer film separation solutionwas controlled to a temperature of 30 to 60&#xb0; C., and a laminated glasswith glass platescrushed is introduced into a barrelfrom a lid portion, and simultaneously,tometal piecesare, introduced into the barrelfrom the lid portionin order to easily separate the laminated glassinto the glass platesand an interlayer film. The barrelcontaining the laminated glassand the metal piecesintroduced thereinto is rotated at a predetermined rotational speed.

Interlayer film separation method

An ultraviolet and infrared radiation absorbing glass is disclosed, comprising, in % by weight:

Ultraviolet and infrared radiation absorbing glass

A magnetic disk in which a texture is formed in a first region spaced apart from an opening formed in a glass substrate by a predetermined distance, and a lubricant is coated on only the texture. The texture is not formed in a second region serving as a data surface, and an undercoating film, a magnetic recording film, and a protective film are sequentially coated on the surface of the glass substrate. In this magnetic disk, a floating amount of a magnetic head can be set to be small, and high-density data can be recorded. The data surface can be free from contamination by dust.
