An abrasive article includes a bonded abrasive body having abrasive particles comprising microcrystalline alumina (MCA) contained within a bond material. In an embodiment, the bonded abrasive body has a strength ratio (MOR/MOE) of at least about 0.80. Additionally, the bonded abrasive body may have a MOR of at least 40 MPa for a MOE or at least about 40 GPa and the bonded abrasive body may be capable of grinding a workpiece that includes metal at a speed of at least about 60 m/s at a material removal rate of at least about 0.4 in/min/in (258 mm/min/mm).

Abrasive article for high-speed grinding operations

An abrasive article can include a bonded abrasive body having abrasive particles comprising microcrystalline alumina (MCA) contained within a bond material. In an embodiment, the bonded abrasive body has a porosity of at least about 42 vol % of the total volume of the bonded abrasive body. Additionally, in an embodiment, the bonded abrasive body is capable of grinding a workpiece comprising metal at a speed of at least about 60 m/s at a material removal rate of at least about 0.4 in/min/in (258 mm/min/mm).

An abrasive article including a body having a bond material and abrasive particles contained in the bond material, the abrasive particles including a composite composition having alumina (AlO), iron oxide (FeO), and silica (SiO). The abrasive particles further include an aspect ratio of at least 1:1 and an average porosity in a range of about 0 vol % to not greater than about 15 vol %.

Abrasive article comprising abrasive particles of a composite composition

An abrasive article including a bonded abrasive body having a bond material present in an amount of not greater than about 15 vol % for the total volume of the body, abrasive particulate material contained in the bond material, the abrasive particulate material including abrasive agglomerates and unagglomerated abrasive particles, wherein the body comprises an abrasive particulate ratio (APp:APagg) within a range between 3:1 and about 1:3, wherein APp represents the amount (vol %) of unagglomerated abrasive particles present in the body and APagg represents the amount (vol %) of abrasive agglomerates present in the body, and a porosity of at least about 42 vol % of the total volume of the bonded abrasive body.

Abrasive article for ultra high material removal rate grinding operations

The subject of the invention is a transparent substrate, especially made of glass, which is provided with an electrode, especially for a solar cell, comprising a conductive layer based on molybdenum Mo with a thickness of at most 500 nm, especially at most 400 nm or at most 300 nm or at most 200 nm.

Transparent substrate equipped with an electrode

The subject of the invention is glazing which incorporates at least one electrically controllable system having variable optical and/or energy properties, especially in the form of a system comprising one or more reversible-insertion materials of the electrochromic-system type, in the form of an optical-valve or viologen-based system or in the form of a liquid-crystal or cholesteric-gel system. This glazing also includes at least one means for adjusting the optical appearance conferred on the said glazing by the said system, these means comprising at least one coating having antireflection properties in the visible.

Glazing with optical and/or energetic properties capable of being electrically controlled

A glazing is described, which includes at least one active layer and at least one reflecting coating on the active layer. A pane, partition, mirror, or door is also described that includes the glazing. A method for making is also described. The glazing exhibits superior thermal and radiative durability, and is capable of modulating the optical appearance of the active layer.

Glazing with variable optical and/or energetic properties

The invention relates to a unit with variable optical properties, which combines at least one system with variable light transmission/absorption, especially of the electrochromic or viologen type, with at least one system with variable light diffusion, especially of the optical valve type or with liquid crystals. The systems are electrically control-driven in order to modulate in a decorrelated manner the light transmission level and the light diffusion level of the unit.
