Introduction

Don’t you love your smartphone? Everyone does. To keep them safe, you must have an excellent screen protector. You may be thinking now, I use my phone with care. But, my buddy, mishaps do happen.

Advanced Ceramics for Superior Smartphone Protection

Protecting your smartphone display is important in today’s digital age. Interestingly, advanced ceramics is a more recent development. They are far more successful at protecting your phone than traditional tempered glass.

These unique materials are quite hard and can withstand scratches and shocks, including large falls. They protect our phones by making them extremely durable against the impact of all these dangerous conditions.

The Role of Cover Glass in Smartphones

You know what? Smartphone cover glass is used on the outer layer of your phone. Their main purpose is to protect the display screen or rear panel. Cover glass is necessary not only to protect cell phones, but also to be portable, comfortable, and eye-catching.

Your phone touches many surfaces and items daily, like coins, keys, and even the corners of tables and floors. Then, an advanced ceramics screen protector acts as a shield between these abrasive materials and your phone screen. It absorbs scratches and keeps the screen itself safe.

So, Let’s check the top 3 types of glass cover materials for your smartphones:

Aluminosilicate Glass – The Industry Standard

Now let’s talk about aluminosilicate glass. This is made up of a substance called aluminum silicate, as the name shows. This glass is particularly resistant to high temperatures and chemical agents.

You’ve probably heard about, Gorilla Glass being a form of aluminosilicate. It is simply a brand name. Corning makes this unique glass, which is thin but durable. They use an ion exchange method to make it strong.

Properties of Aluminosilicate Glass

Want to know more? Some properties of the Aluminosilicate glass screen protector are here:

  • Resistance to Scratch and High Tensile Strength: Due to their resistance to scratches, which are found on mobile devices, aluminosilicate is widely used in glass screen manufacturing.

  • Resistance to High Temperature: With an annealing temperature of up to 800°C, aluminosilicate provides glass with a high level of thermal resistance. It’s near the same temperature as ceramics.

  • Resistance to chemical degradation: Aluminosilicate is highly chemically resilient, having a decomposition rate of 10-4 g/(m2·day).

Yet, in comparison to advanced ceramics, aluminosilicate glass has limits, particularly in terms of impact resistance and general longevity. Advanced ceramics, because of their extreme hardness, provide greater protection.

Production of Aluminosilicate Glass

Ion exchange is the process used to produce Gorilla Glass. The glass is immersed in molten potassium salt at 400 degrees Celsius. In this way, potassium transfers sodium atoms out of the molecule.

Tempered Glass – A Popular Alternative

Interestingly, a tempered glass screen protector is to be chosen over a regular plastic protector. Since the former comprises a hard and sturdy material that is capable of withstanding scratches, cracks, and even minor falls. However, This does not always result in durability as the advanced ceramic materials offer.

Properties of Tempered Glass

So, The following are the best properties of a tempered glass screen protector:

  • Enhanced durability: Tempered glass is produced by using heat and chemicals on ordinary glass. It strengthens it and increases its resistance to cracking and scratching.

  • Better clarity: The tempered glass keeps the quality of your smartphone’s screen, helping to enjoy brilliant colors and sharp images without deformation.

  • Smudge and fingerprint resistance: Tempered glass protectors contain a unique coating that hinders smudges and fingerprints. It keeps your smartphone’s screen clean and transparent.

Unlike liquid glass, tempered glass protectors have a 9H hardness and are much more durable. It is resistant to scratches from sharp objects like knives and most small drops and falls. The drawback, though, is that it can break when damaged by massive loads, such as a large drop.

Production of Tempered Glass

Now, let’s move on to the process of tempered glass. It can be produced from annealed glass through the thermal tempering method. The glass was set on a roller table and passed through a furnace. The furnace heated it above its initial temperature of 564 °C (1,047 °F) to 620 °C (1,148 °F).

After that, forced air drafts quickly cool the glass, leaving the inside free for movement for a brief time.

Ceramic Glass – The Advanced Material

Let me just say that here’s the best part! Inorganic ceramic films are also referred to as hard screen protectors. They are among the best types of screen protectors available in the market. It is becoming popular because it has given high performance compared to older technologies such as tempered glass.

Low weight, improved strength, and better thermal and chemical stability are other advantages of advanced ceramics. That’s why it gives peace of mind to customers.

It consists of titanium, zirconia, and alumina. Advanced ceramics normally can withstand from 1000 °C to 1600 °C (1800 F to 3000 F) temperature ranges. Therefore it is ideal for covering the screen of a mobile phone and is durable.

Properties of Ceramic Glass

Don’t overlook their properties. Ceramic glass screen protectors are well-liked because of their high scratch-resistant and protective properties.

  • Scratch Resistance: A super scratch-proof ceramic screen protector helps your mobile’s screen not crack even if you accidentally drop it.

  • Oleophobic Coating: Most ceramic protectors use an oleophobic layer that makes the glass interface even better. It provides a better seal against water and oil hence improving the soft touch and easy-to-clean layer.

  • High Transparency: They maintain the original clarity of the display screen as compared to traditional protectors, providing a clear and colorful representation.

  • Thin Profile: Although ceramic protectors are tough, they are usually very slim, thus maintaining the aesthetic look.
