Explanation:

• In this method pure silica sand (SiO2) and finely ground coke (carbon) are mixed together.
• Then heated to very high temperatures in an electric furnace.
• It can be formed as a fine powder or a bonded mass that must be crushed and milled before it can be used as a powder feedstock.
