20090117382 | Ultrafine nepheline syenite - A useable particulate nepheline syenite having a grain size to provide an Einlehner Abrasive Value of less than about 100 is described. The particulate nepheline syenite is generally free from agglomeration and moisture free. At least 99% of the nepheline syenite particles have a size less than 10 microns. In practice, the nepheline syenite grain size is less than about 5 microns and the distribution profile of the particulate system is generally 4-5 microns. | 05-07-2009 |
20110123804 | ULTRAFINE NEPHELINE SYENITE - A useable particulate nepheline syenite having a grain size to provide an Einlehner Abrasive Value of less than about 100 is described. The particulate nepheline syenite is generally free from agglomeration and moisture free. At least 99% of the nepheline syenite particles have a size less than 10 microns. In practice, the nepheline syenite grain size is less than about 5 microns and the distribution profile of the particulate system is generally 4-5 microns. | 05-26-2011 |
20120263954 | NEPHELINE SYENITE POWDER WITH CONTROLLED PARTICLE SIZE AND NOVEL METHOD OF MAKING SAME - An ultra-fine inorganic powder for use as a filler and formed from a hard, naturally occurring mined material, in particular nepheline syenite, where the powder has a targeted controlled maximum particle size of less than 5 microns and a generally uncontrolled minimum particle size. | 10-18-2012 |
20130253098 | MINERAL BASED FILLERS USED AS A SUBSTITUTE FOR WOOD FILLERS IN SIMULATED WOOD PRODUCTS AND SIMULATED WOOD PRODUCTS CONTAINING THE SAME - A simulated wood product such as decking, fencing and architectural trim of the type heretofore made from a plastic with a natural wood powder as filler, wherein at least most, if not all, of the wood powder is replaced by a powder formed from a hard naturally occurring mineral, such as nepheline syenite or feldspar. | 09-26-2013 |
20140306038 | POWDER FORMED FROM MINERAL OR ROCK MATERIAL WITH CONTROLLED PARTICLE SIZE DISTRIBUTION FOR THERMAL FILMS - An ultra-fine powder formed from a naturally occurring mineral or rock material and having a controlled or “engineered” particle size distribution (PSD) to match the infrared spectra with a maximum particle size in the range of 14-17 microns measured as either D99, or preferably D95, and a minimum particle size D5 in the range of 4-7 microns. Preferably the maximum particle size is about 15 microns, the minimum particle size is about 5 microns and the D50 particle size is about 8-10 microns with the moisture content of the particle size “engineered” powder being less than about 0.20 percent by weight and preferably about 0.05 to 0.08 percent by weight of the powder. This specially “engineered” ultra-fine powder is used to reduce the thermicity of thermal film to a value less than about 20%. | 10-16-2014 |
20140377527 | ULTRA FINE NEPHELINE SYENITE POWDER AND PRODUCTS FOR USING SAME - Nepheline syenite powder with a controlled particle size where 99.9% of the particles are less than about 10 microns and preferably less than about 6 microns, which powder has a moisture content of less than 0.8% and an Einlehner Abrasive Value of less than 100 and products using this fine grain ultra fine nepheline syenite powder. | 12-25-2014 |
20150017445 | ULTRAFINE NEPHELINE SYENITE - A useable particulate nepheline syenite having a grain size to provide an Einlehner Abrasive Value of less than about 100 is described. The particulate nepheline syenite is generally free from agglomeration and moisture free. At least 99% of the nepheline syenite particles have a size less than 10 microns | 01-15-2015 |
20150218339 | NEPHELINE SYENITE POWDER WITH CONTROLLED PARTICLE SIZE AND NOVEL METHOD OF MAKING SAME - An ultra-fine nepheline syenite powder produced from a pre-processed nepheline syenite powder feedstock. The powder having a “controlled” maximum grain size D95 or D99 of less than about 20 microns and a “controlled” minimum grain size D5 in the range of 2-8 microns with a particle size spread D5-D95 of less than about 12 microns. | 08-06-2015 |
