A composition having a plurality of abrasive particles including alumina, the plurality of abrasive particles have mesoporosity with an average meso branching index of at least 55 junctions/micronsand a median particle size (D50) of at least 5 microns.

Composition including a plurality of abrasive particles and method of using same

A composition can comprise a carrier including a liquid and an abrasive particulate contained in the carrier, the abrasive particulate having, on average, at least 10 wt % cerium oxide in the abrasive particulate and a cerium 3+ ratio (Ce 3+/total cerium) of at least 0.1. In another embodiment, a slurry composition can comprise a liquid carrier comprising water, cerium oxide particles, and free silicate ions, wherein a material removal rate when polishing a silicon oxide wafer can be is increased by at least 3% in comparison to a slurry composition not including free silicate ions.

Composition for conducting material removal operations and method for forming same

The present disclosure is directed to an alpha alumina powder having a specific surface area, a specific crystallite size, and a specific particle size distribution for use in abrasive polishes, and method of making such powder. The method of making the alpha alumina powder can include calcining an aluminum oxide precursor powder at a temperature of 800-1500&#xb0; C. and milling the calcined powder to the specific particle size distribution. The alpha alumina powder disclosed herein can quickly enable high removal rate with undiminished aesthetic quality when used in abrasive polishes.

Alumina abrasive particles used for automotive finishing compositions

A composition including a carrier comprising a liquid, an abrasive particulate contained in the carrier, an accelerant contained in the carrier, the accelerant including at least one free anion selected from the group of iodide (I), bromide (Br), fluoride (F), sulfate (SO), sulfide (S), sulfite (SO), chloride (Cl), silicate (SiO), phosphate (PO), nitrate (NO), carbonate (CO), perchlorate (ClO), or any combination thereof, and a buffer contained in a saturated concentration in the carrier, the buffer including a compound selected from MF, NF, MNF, MI, NI, MNI, MBr, NBr, MNBr, M(SO), N(SO), MaN(SO), MS, NS, MNS, M(SiO), N(SiO), MN(SiO), M(PO), N(PO), MN(PO), M(NO), N(NO), MN(NO), M(CO), N(CO), MN(CO), or any combination, wherein M represents a metal element or metal compound; N represents a non-metal element; and a, b, and x is 1-6.

An armor component including a body having a first portion including calcium boride compounds include non-stoichiometric calcium boride (CaB) and stoichiometric calcium boride (CaB) and having a density of at least about 80% theoretical density. In one aspect, the first portion can include a first phase comprising silicon carbide (SiC) and a second phase comprising calcium boride (CaB). In another aspect, the first portion can further include a third phase comprising boron carbide (BC).
