A manganese-zinc ferrite with a high magnetic permeability at negative temperature and low loss at high temperature consists of Fe.sub.2O.sub.3, MnO and ZnO, and additives consisting of CaCO.sub.3, ZrO.sub.2, Co.sub.2O.sub.3 and SnO.sub.2 are also added. A method for preparing the manganese-zinc ferrite is further provided. According to the method, by reasonably adjusting a ratio of Mn to Zn to Fe and appropriately increasing the content of Co in the additives, a manganese-zinc ferrite material with both a high magnetic permeability and low loss at about −20° C. and low loss at 120-140° C. is obtained. The manganese-zinc ferrite material has two loss valleys at about −20° C. and about 100° C. in a temperature range of −30° C. to 140° C., which expands the application range of the manganese-zinc ferrite material.

Provided is a powder material for forming a three-dimensional object, the powder material containing granulated particles containing: a resin; and inorganic particles of which primary particles have a volume average particle diameter of 1 micrometer or less, wherein the granulated particles have a volume average particle diameter of 10 micrometers or greater but 70 micrometers or less and a BET specific surface area of 6 m.sup.2/g or greater but 8 m.sup.2/g or less.

A porous fired granulated body is formed by consolidating numerous alumina particles to each other while letting mainly interconnected pores remain in network form across an entire cross section of a granulated body particle (11). The pores (13) have an inner diameter controlled by a droplet diameter of a pore forming agent and have numerous precipitated alumina crystals (15) formed on inner surfaces thereof. Manufacture is performed by spraying the pore forming agent (emulsion) onto a raw material to form a coating layer of the pore forming agent on a surface of the raw material particle and controlling the inner diameter of the pores. A porous fired granulated body of alumina having a high specific surface area and having higher strength for the same specific surface area can thus be provided by a simple manufacturing method.

The present invention relates to a granular thermal insulation material comprising hydrophobized silicon dioxide and at least one IR opacifier, having a tamped density of up to 250 g/l and a compressive strength according to DIN EN 826:2013 at 50% compression of 150 to 300 kPa or greater than 300 kPa, to processes for production thereof and to the use thereof for thermal insulation.

The present disclosure describes a lithium solid state battery, including a cathode that includes an active material such as lithium, and an additive having a lower melting point than the active material.
