| titleOfInvention | Spherical forsterite particles, method for producing same, and resin composition containing spherical forsterite particles |
| abstract | The invention provides a substrate having improved high-frequency characteristics, which is produced from forsterite having a low dielectric loss tangent and a spherical particle shape. The solution is to provide forsterite particles having an average particle diameter of 0.1 to 10 μm and a dielectric loss tangent of 0.0003 to 0.0025. The degree of sphericity (average particle diameter measured by a laser diffraction particle size distribution measuring device: μm)/(average primary particle diameter converted from the specific surface area by a nitrogen adsorption method: μm) is 1.0 to 3.3. A method for preparing forsterite particles, and its packageComprises the following steps: (A) the process comprises the following steps: magnesium compound as magnesium source and silicon compound as silicon source are mixed with MgO/SiO of magnesium and silicon 2 A step of mixing the materials so that the molar ratio of the materials is 1.90 to 2.10 to prepare forsterite particles, and (B) a step of: a step of charging the forsterite particles prepared in the step (a) into a hydrocarbon combustion flame to collect forsterite particles, and a step (C) of: firing the forsterite particles obtained in the step (B) at 700 to 1100 ℃. The ratio of the resin to the forsterite particles is 1: 0.001 to 1000. |
