Ceramic and Tile

Zirconium silicate occurs in nature as mineral zircon. Ore is mined from natural deposits and concentrated by various techniques. It is separated from sand by electrostatic and electromagnetic methods.
Also, the compound can be made by fusion of SiO2 and ZrO2 in an arc furnace, or by reacting a zirconium salt with sodium silicate in an aqueous solution.
Zirconium silicate is used for manufacturing refractory materials for applications where resistance to corrosion by alkali materials is required. It is also used in production of some ceramics, enamels, and ceramic glazes. In enamels and glazes it serves as an opacifier. It can be also present in some cements. Another use of zirconium silicate is as beads for milling and grinding. Thin films of zirconium silicate and hafnium silicate produced by chemical vapor deposition, most often MOCVD, can be used as a high-k dielectric as a replacement for silicon dioxide in semiconductors. 
Zirconium silicates have also been studied for potential use in medical applications. For example, ZS-9 is a zirconium silicate that was designed specifically to trap potassium ions over other ions throughout the gastrointestinal tract.[3] It is undergoing clinical trials for the treatment of hyperkalemia 
Zirconium disilicate is used in some dental crowns because of its hardness and because it is chemically nonreactive.

Sodium tripolyphosphate is an excellent cleaning agent and is used in detergent, ceramic tiles, water treatment, metal treatment and paints
This chemical is a white, solid powder. It does not produce any odor, but it does leave a slight alkaline taste when ingested. It is stable in the air and highly soluble in water. Sodium tripolyphosphate is typically referred to as STPP, which is how it appears on most labels. It is not very toxic and non-flammable.
One of the primary uses for STPP is as a water softener in many types of detergent. This helps to ensure that they work properly in hard water. Another primary purpose for STPP is to preserve a variety of food products, such as seafood, poultry, and animal feeds. It acts as an emulsifier as well as a way to maintain moisture in the meat. STPP is generally regarded as safe (GRAS) by the FDA.
Since this substance is stable and only slightly toxic, it does not need extra care and attention. It should be stored in a cool, dry area and kept sealed so that it doesn’t interact with anything in the air. It may create mild irritation of the skin or eyes, and it is only harmful if ingested in large quantities.

Sodium tripolyphosphate is produced in the following technical grades:

• Fine
• Granular (low density granular, medium density granular, high density granular)
• High temperature rise
• Medium temperature rise
• Low temperature rise
