Product Name

γ-Alumina oxide Nanopowder

Product Overview

High purity aluminium oxide (Al2O3) has several crystalline forms, of which α-phase and γ-phase are the two main variants. γ-phase aluminium oxide belongs to the cubic crystal system and has a spinel structure. This structure consists of nano-sized particles with aluminium atoms irregularly arranged in octahedral and tetrahedral pores surrounded by oxygen atoms. γ-phase alumina is formed at low temperatures (within the range of 500~700°C), which has a uniform particle size distribution, high purity, a high specific surface, inertness against high temperatures, high activity, and is an active alumina, and is currently used most notably as a carrier for catalysts in the fields of Petrochemical industry, environmental protection and other fields.

Technical Parameter 

 

Purity:9.9 wt%

Particle size:0-15 nm

SSA:20 m2/g   

Product Features

 

Large specific surface area: rich pore space and large specific surface area. 

High surface activity: a large number of hydroxyl groups and unsaturated bonds exist on the surface, with high chemical activity. 

Adjustable pore structure: the pore size and pore volume can be adjusted by controlling the preparation conditions. 

Good adsorption performance: it can effectively adsorb various molecules and ions.

Application Fields

 

Abrasion Resistant Agent and Coating: Used as rubber abrasion resistant agent and coating scratch resistant agent to improve the durability and protective properties of materials.

Catalyst and carrier: Due to its high surface activity and large specific surface area, it is often used as a catalyst or carrier for catalysts, such as hydrogenation and dehydrogenation reactions in petrochemical industry. For example, in automobile exhaust gas purification catalyst, γ-phase alumina can be loaded with precious metals such as platinum and palladium to improve catalytic efficiency. 

Adsorbent: It is used to adsorb impurities and harmful substances in gases and liquids, such as removing heavy metal ions in water treatment. It can effectively adsorb heavy metal ions such as copper and lead in wastewater.

Ceramic material additives: used as additives in ceramic manufacturing to improve the performance of ceramics. It can improve the moulding performance and sintering activity of ceramics.

They’re fantastic!!!!
Size: X-Large, Color: Multicoloured E-(5-pack)
My clothing size is 16/18 and XL. Even though Amazon suggested a size XXL, I ordered my normal XL and they fit perfectly. The fabric for this style is 92% bamboo viscose and is amazingly soft and almost silky feeling. I had ordered a different boy short in this brand but they were 80% bamboo viscose and the fabric was significantly heavier. I returned those and ordered these.

Comfortable, breathable, and flattering
Size: Small, Color: Pink/White/Khaki/Blue/Brown
I’m really pleased with this set of cotton women’s boxer shorts. The fabric is genuine cotton and feels lightweight and breathable without feeling flimsy or cheap. They’re comfortable enough to wear all day, especially if you prefer natural fibers. The elastic waistband is soft, comfortable, and also really cute, it doesn’t dig in or feel restrictive at all. The fit is true to size. I usually wear a small in underwear and these fit me perfectly. They feel secure while still looking sexy and relaxed at the same time, which is a great balance. I also really appreciate the earthy color palette, it feels calm, natural, and wearable rather than overly bright or synthetic. Overall, these are well-made, comfortable, and thoughtfully designed, and I’d happily order them again.

Lightweight and Comfortable.
Size: Small, Color: Pink/White/Khaki/Blue/Brown
These cotton boy shorts are really comfortable and soft. The material is breathable and feels nice on the skin, not itchy or tight. The size small fits true to size and stays in place without rolling up. I like the striped design and how they give good coverage while still feeling lightweight. Great for everyday wear and easy to wash. Overall, a solid and comfy underwear set.

Great toddler backpack!
Size: Small, Color: All Black
My daughter is in prek 3 and loves this backpack. Nice and small for her to carry. A full folder will fit with a little force, but if you’re looking for something to actually carry folders and books, maybe not the best.

“Tiny Backpack, Big Personality!”
This little backpack is doing big kid things — and my toddler knows it. The second we strapped it on, he marched around like he was off to close a business deal with juice boxes in both hands. It’s the perfect size for tiny shoulders, and the chest buckle? GENIUS. No more slippy straps or bag-flinging tantrums. It stays put like a champ, even during epic playground sprints and spontaneous dance moves in the grocery store. The material is sturdy, the zippers glide like butter, and the reflective strip makes my toddler look like he’s ready for a baby night shift. The color combo is sleek — black and grey with just the right touch of “cool kid on campus” energy. Plenty of space for snacks, sippy cups, a favorite toy, and 14 mysterious pebbles he insisted on collecting “for science.” If your 2-4-year-old wants to carry their own stuff and look proud doing it — this is the backpack for them. Highly recommend (and yes, I already ordered another one for backup... because toddlers). 🎒
