Synthesized siliconironpeach and manufacturing method thereof

The invention discloses a synthetic ferrosilicon red and preparing method thereof. Weight percent of main raw materials for the synthetic ferrosilicon red are: anhydrous ferric carbonate of 8-60%, white carbon black of 40-92%; the white carbon black is heavy, pH value is neutrality; the anhydrous ferric carbonate is industrial level and is low label ferric chloride red. The preparing method includes steps of: material mixing, sphere grinding, loading, and sintering. The sphere stone is made of silicon, time of sphere grinding is 18-20 h, time of heating up is 16 h, time of heat preservation is 3 h, and sintering temperature is 1000-1100 DEG C. Advantages of the invention are: pattern of products is abundant, decorative effect is increased remarkably, preparing process is simple, cost is 25% lower than cost of import, each property exponent of the synthetic ferrosilicon red is batter than natural ferrosilicon red, thereby the synthetic ferrosilicon red can replace the natural ferrosilicon red completely and possesses wide market economic benefit.
