Metallic?silicon?powder,?also?known?as?industrial?silicon?powder,?is?silver?gray?or?dark?gray?powder?with?metallic?luster.?It?has?high?melting?point,?good?heat?resistance,?high?resistivity?and?high?antioxidant?effect.?It?is?called?"industrial?monosodium?glutamate"?and?is?an?indispensable?basic?raw?material?for?many?high-tech?industries.

At?present,?the?mainstream?processes?of?metal?silicon?powder?are?Raymond?process,?impulse?spinning?process,?disk?grinding?process?and?counter?roll?process.?Domestic?enterprises?mainly?use?horizontal?and?vertical?impulse?spinning?processes.?The?future?development?trend?of?the?product?will?be?more?refined?and?environmental?friendly,?so?the?process?will?develop?towards?efficiency?and?environmental?protection?in?the?future.

In?recent?years,?affected?by?the?government's?environmental?protection?policies?and?the?industry's?resolution?of?overcapacity?and?related?industries,?the?price?of?metal?silicon?powder?has?risen,?and?the?market?prospect?is?good.

According?to?the?investigation?of?research?on?metal?silicon?powder?industry?released?by?CMRC?Zhongyan?Century?Consulting,?the?downstream?application?fields?of?metal?silicon?powder?mainly?include?silicone?industry,?silicon?aluminum?alloy?industry?and?polycrystalline?silicon?industry.?The?price?difference?of?metal?silicon?powder?applicable?to?the?three?fields?is?small,?but?the?demand?characteristics?are?obviously?different.

Silicone?industry:?after?purchasing?silicon?blocks,?silicone?will?be?processed?into?silicon?powder?according?to?demand.?Domestic?silicone?enterprises?generally?purchase?according?to?national?standards.?Because?the?industry?uses?metal?silicon?powder?for?chemical?reaction,?there?are?requirements?for?particle?size.

Silicon?aluminum?alloy?industry:?limited?by?smelting?furnace?and?smelting?process,?enterprises?have?particle?size?requirements?for?silicon?blocks.?Smelting?furnaces?of?different?sizes?have?different?requirements.?10mm-100mm?is?a?typical?particle?size?requirement.

Polycrystalline?silicon?industry:?polycrystalline?silicon?is?mainly?used?in?photovoltaic?industry?and?semiconductor?materials.?Most?enterprises?usually?purchase?silicon?powder?directly?from?the?silicon?powder?factory,?which?is?responsible?for?processing?industrial?silicon?blocks?into?silicon?powder.?Therefore,?the?polycrystalline?silicon?industry?has?no?special?requirements?for?the?particle?size?of?industrial?silicon.?As?the?photovoltaic?industry?needs?chemical?reaction,?there?are?requirements?for?the?particle?size.?Driven?by?the?rapid?development?of?photovoltaic?industry?in?recent?years,?polysilicon?has?the?greatest?potential?in?the?future.
