A flame retardant comprising (A) ethylenediamine-containing zinc phosphate and (B) a metal compound.

Flame retardant and flame retardant resin composition containing it

The subject of the invention is to provide a new high-performance flame retardant having excellent flame resistant effect and smoke-suppressing effect and generating no hazardous gas, and a new flame retardant resin-composition used it. As a means for solution, a flame retardant comprising ethylenediamine-containing zinc phosphate and other phosphorus-containing compound is formulated in amounts of 10 to 200 parts by weight to 100 parts by weight of resin.

Flame retardant and flame retardant resin composition formulated with

An ITO sintered body according to the present invention has a density thereof of between 90 and 100% and a sintering particle size of between 1 and 20 .mu.m. A proportion of (In.sub.0.6 Sn.sub.0.4).sub.2 O.sub.3 in the ITO sintered body is 10% or below. Such an ITO sintered body is manufactured by mixing an indium oxide powder, whose BET surface area is between 15 and 30 m.sup.2 /g, a BET size/a crystallite size is 2 or below, and an average primary particle size is between 0.03 and 0.1 .mu.m, with tin oxide whose BET surface area is 3 m.sup.2 /g or below, and then by sintering the mixture.
