SUBSTRATE, HAVING A THIN-LAYER SYSTEM WITH THERMAL PROPERTIES, COMPRISING AT LEAST ONE LAYER OF NICKEL OXIDE Russian patent published in 2020 - IPC C03C17/36 

FIELD: glass industry.

SUBSTANCE: invention relates to a transparent substrate, in particular from a rigid mineral material, such as glass, and can be used to produce heat-insulating and/or sun-protective glazing. In particular, disclosed is transparent substrate (30), provided on one main side with a thin-layer system comprising at least one and even only one metal functional layer (140), capable of reflecting infrared and/or solar radiation, particularly based on silver or metal alloy containing silver, and two antireflecting coatings (120, 160). Each of said antireflection coatings comprises at least one dielectric layer (122, 126; 162, 168), and said functional layer (140) is located between said two antireflection coatings (120, 160). At least one layer of nickel oxide Ni_xO (135) is lower and in contact with functional layer (140) in direction from said substrate (30), and the physical thickness of said nickel oxide layer Ni_xO (135) is at least 0.3 nm, or 0.6 to 8.0 nm, or 1.0 to 5.0 nm.

EFFECT: technical result is reduction of surface resistance and, consequently, reduction of emissivity, after one or several high-temperature heat treatments such as bending, and/or quenching, and/or annealing, and/or instantaneous heating.
