Abstract: Aluminosilicate microcrystalline glass, and a manufacturing method and a product thereof, where in addition to a glass phase, the aluminosilicate microcrystalline glass includes principal crystalline phases: a magnesium aluminate (MgAl2O4) crystal including a volume percentage of 5% to 30%, a lithium disilicate (Li2Si2O5) crystal including a volume percentage of 10% to 30%, and a quartz and quartz solid solution including a volume percentage of 5% to 30%. Residues are other inevitable impurities. The inevitable impurities include intermediate products generated when the MgAl2O4 crystal, the Li2Si2O5 crystal, or the quartz and quartz solid solution is being generated, other impurities that are inevitable in a glass production process, and the like.

Abstract: A metal enclosure of a mobile device, a production method for the metal enclosure, and a mobile device are disclosed. The metal enclosure of a mobile device includes a housing, where at least one gap is disposed on the housing, and the at least one gap divides the housing into at least two electrically insulated parts. The metal enclosure further includes an insulation film attached to a surface of the housing. In the foregoing embodiments, the gap is provided on the housing, so that the housing is divided into the at least two electrically insulated parts. Each gap is filled with an insulation object, and the gap on the surface of the housing and the insulation object in the gap form a partition.
