摘要： 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%.

摘要： Methods of converting olivine to lizardite without formation of chrysotile or brucite are disclosed. The methods comprise heating a mixture of olivine, silica, water, and a caustic agent. The addition of silica allows for complete conversion of the olivine to lizardite through a more thermodynamically favorable reaction. The olivine and silica are preferably of small particle size to increase reactivity.
