The high-alumina ceramic granulated powder prepared by a similar formula is used for downstream products, and a cloud spot phenomenon appears on a user's response, so that the product appearance is influenced, and the product is also brittle and cracked in the use process.
Disclosure of Invention
According to the production formula of the calcium-magnesium-salt-free high-alumina ceramic granulated powder, aiming at the cloud spot phenomenon which influences the attractiveness and the embrittlement of the product, the cloud spot phenomenon is caused by the calcium-magnesium salt in the original formula through analysis and experiments, so that the calcium-magnesium-salt-free formula is developed, the embrittlement problem is considered, and silicon dioxide, lanthanum oxide, strontium carbonate, yttrium oxide and talcum powder are added to improve the toughness of the product.
In order to solve the technical problems, the technical scheme adopted by the invention is as follows:
a production formula of calcium-magnesium salt-free high-alumina ceramic granulated powder comprises lanthanum oxide, strontium carbonate, kaolin, yttrium oxide, talcum powder, silicon dioxide and aluminum oxide.
The formula comprises the following components in percentage by weight:
lanthanum oxide: 0.10 to 2.0 percent;
strontium carbonate: 0.1 to 3.0 percent;
