Abrasive Grain Comprising Manganese Oxide

View page
US Patent:
56907079, Nov 25, 1997
Filed:
Jun 2, 1995
Appl. No.:
8/459548
Inventors:
William P. Wood - Golden Valley MN
Henry A. Larmie - Oakdale MN
Assignee:
Minnesota Mining & Manufacturing Company - St. Paul MN
International Classification:
C09C 168
US Classification:
51309
Abstract:
Abrasive grain including manganese oxide therein are provided. The inclusion of manganese oxide can be utilized to reduce the transition temperature of transitional alumina(s) to alpha alumina(s), during the formation of the abrasive grain. Further, manganese oxide presence can be utilized to generate sintered abrasive grain having a submicrometer, faceted microstructure. The abrasive grain are useful in abrasive articles such as coated abrasives, three-dimensional, low density abrasives, and bonded abrasives.

Method For Making Abrasive Grain Containing Alumina And Ceria

US Patent:
54296471, Jul 4, 1995
Filed:
Jan 13, 1994
Appl. No.:
8/181474
Inventors:
Henry A. Larmie - Oakdale MN
Assignee:
Minnesota Mining and Manufacturing Company - St. Paul MN
International Classification:
C09C 168
US Classification:
51295
Abstract:
A method of preparing abrasive grain includes: preparing a dispersion including alpha alumina oxide monohydrate and ceria sol therein; converting the dispersion to base grit material; and sintering the base grit to form abrasive grains. The grain are useful in abrasive products.

Abrasive Grain Containing Alumina And Zirconia

View page
US Patent:
55519636, Sep 3, 1996
Filed:
Nov 6, 1995
Appl. No.:
8/554033
Inventors:
Henry A. Larmie - Oakdale MN
Assignee:
Minnesota Mining and Manufacturing Co. - St. Paul MN
International Classification:
B24D 334
US Classification:
51307
Abstract:
A method of preparing preferred abrasive grain includes: preparing a dispersion including alpha alumina oxide monohydrate and zirconia sol therein; converting the dispersion to base grit material; and sintering the base grit to form abrasive grains. The presence of the zirconia sol within the dispersion from which the base grits are formed provides an improved abrasive grain. The improved abrasive grain are useful in abrasive products.

Abrasive Grain Having Rare Earth Oxide Therein

View page
US Patent:
54982693, Mar 12, 1996
Filed:
May 26, 1995
Appl. No.:
8/453572
Inventors:
Henry A. Larmie - Oakdale MN
Assignee:
Minnesota Mining and Manufacturing Company - St. Paul MN
International Classification:
B24D 1100
B24D 1102
US Classification:
51295
Abstract:
A preferred abrasive grain comprises a sintered product of a precursor material comprising alumina, zirconia, and rare earth oxide. The preferred abrasive grain has an average hardness of at least about 21 GPa and an average toughness of at least about 4 MPa. multidot. m. sup. 1/2. A method of preparing preferred abrasive grain is provided. The improved abrasive grain are useful in abrasive products.
