Abstract
The invention discloses a method for manufacturing aluminum ceramic microspheres in mullite toughening, which is characterized in that the aluminum ceramic microspheres in the mullite toughening are prepared from clay, magnesium clay, Suzhou soil, alpha-Al2O3, Jingdezhen pottery stone, feldspar and tabular spar by blending, grinding, rolling to form balls, drying, baking and cooling. The Al2O3 containing substance is used as the raw material for blending so as to save the resource, reduce the cost of the raw materials and improve the abrasion resistance and compressive strength. The method can greatly reduce the production cost, improve the abrasion resistance of the aluminum ceramic microspheres in the mullite toughening, increase the hardness and density, reasonably utilize the waste slag and well protect the environment.

On the market present in China, these series product mainly comprise kinds such as aluminum oxide, zirconium white, silit, silicon nitride, wherein with ZrO
2Porcelain ball and alumina porcelain ball (75-95%Al
2O
3) be the main supply and demand object in market.But ZrO
2And Al
2O
3Cost an arm and a leg, manufacturing cost is high, does not have a market advantage.So exploitation Al
2O
3The middle aluminium porcelain of content≤60% because of its mature production technology, production line are invested little, product price ratio height, and becomes the main flow articles for use of current mineral products, powder processing industry, and consumption is maximum, and purposes is very wide.But that present composition of raw materials is used is Al
2O
3Raw material, its cost is higher, if the wear resistance of the middle aluminium porcelain microballon grinding medium that other raw materials of employing then make is not high, density is lower and hardness is lower; Also have the not ideal enough of existing sintering temperature control, cause that to fire cost higher; And waste residue (like mine tailing) can't rationally be utilized in process of production, and making needs a large amount of spaces to stack, and also can cause certain pollution to environment.
Summary of the invention
The objective of the invention is to, the method for making of aluminum ceramic microspheres in a kind of mullite toughening is provided.Adopt the present invention, both can reduce production costs greatly, can improve the wear resistance of aluminum ceramic microspheres in the mullite toughening again, increase hardness and density, and can rationally utilize waste residue, the protection environment.
Technical scheme of the present invention: the method for making of aluminum ceramic microspheres in a kind of mullite toughening is characterized in that: with clay, attaclay, Suzhou soil, α-Al
