본 발명은 금속 코팅된 입자를 형성하는 방법, 이 방법에 따라 제조된 금속 코팅된 입자, 및 이들 금속 코팅된 입자의 용도에 관한 것이다. 이 방법은 코팅될 베이스 입자 원료를 제공하는 단계; 금속-포함 코팅 입자 원료를 제공하는 단계; 및 단계 (a)에 기재된 베이스 입자 및 단계 (b)에 기재된 금속 포함 코팅 입자 원료를 열교환수단을 포함하는 연속 반응기에 주입함으로써 베이스 입자를 코팅 입자 원료와 접촉시켜 그 결과 금속 코팅된 입자를 형성하는 단계를 포함한다. 상기 코팅된 입자는 균질한 코팅을 포함하며, 다양한 분야에 적용될 수 있다. A method of forming metal coated particles comprises the steps of: providing a source of base particles to be coated; providing a source of a metal-comprising coating particles; and feeding the base particles specified in step (a) and the source of metal comprising coating particles specified in step (b) into a continuous reactor including heat exchange means to cause contact of the base particles with the source of coating particles thereby to form the metal coated particles. The base particles may be selected from silicon, germanium, tin, aluminium, gallium, zinc etc. and the source of metal-coating particles may be selected from silver, copper, platinum, iron, cobalt, rhodium, vanadium, nickel, ruthenium, iridium and gold. The coated particles include a homogeneous coating and can be used in a variety of applications. Also shown is the meta-coated particle and the apparatus for performing the method.
