2. Silicon Nitride Ball Specifications

2.1. Material Composition

Silicon nitride balls manufactured by DSP Precision Products Pvt. Ltd. are made from high-quality silicon nitride ceramics. Silicon nitride (Si₃N₄) is a compound consisting of silicon and nitrogen, known for its superior mechanical properties and performance characteristics. The specific material properties include:

• High Purity: The silicon nitride used is of high purity, ensuring optimal performance and reliability in demanding applications.
• Additives: Various additives may be included in the manufacturing process to enhance specific properties, such as sintering aids or stabilizers.

2.2. Mechanical and Physical Properties

• Hardness: Silicon nitride balls exhibit exceptional hardness, typically ranging from 1,200 to 1,600 HV (Vickers Hardness). This high hardness ensures excellent wear resistance and durability.
• Density: Silicon nitride has a relatively low density compared to metals, approximately 3.2 g/cm³. This low density contributes to reduced overall weight in various applications.
• Strength: Silicon nitride possesses high tensile strength and fracture toughness, making it suitable for high-stress applications where reliability is crucial.
• Thermal Stability: Silicon nitride balls exhibit excellent thermal stability, withstanding temperatures up to approximately 1,400°C without significant degradation.
• Chemical Resistance: Silicon nitride is highly resistant to chemical corrosion, including acids and alkalis, making it suitable for harsh environments.

3. Manufacturing Process

3.1. Raw Material Preparation

The manufacturing process of silicon nitride balls begins with the preparation of raw materials. High-purity silicon powder and nitrogen are combined to form silicon nitride. The raw materials are carefully selected and processed to ensure the desired properties of the final product.

3.2. Powder Processing

• Mixing: Silicon powder is mixed with additives and binders to achieve the desired composition and properties. This mixture is thoroughly blended to ensure uniformity.
• Milling: The mixed powder is milled to achieve a fine particle size, which is crucial for achieving high density and strength in the final product.

3.3. Forming the Balls

• Pressing: The fine silicon nitride powder is pressed into spherical molds using hydraulic or mechanical presses. This process forms the rough shape of the balls and is known as the green body stage.
• Injection Molding: In some cases, injection molding techniques are used to shape the green bodies. This method allows for complex geometries and precise control over dimensions.

3.4. Sintering

• Sintering: The green bodies are subjected to a high-temperature sintering process in a furnace. This process involves heating the balls to temperatures exceeding 1,600°C in a controlled atmosphere. Sintering causes the powder particles to fuse, forming a dense and solid ceramic structure.

3.5. Grinding and Finishing

• Grinding: After sintering, the balls are ground to achieve precise dimensions, roundness, and surface finish. This step ensures that the balls meet stringent size and tolerance specifications.
• Polishing: The balls are then polished to remove surface imperfections and enhance their appearance. Polishing also contributes to reducing friction and improving the functional performance of the balls.

3.6. Quality Control

Quality control is a crucial aspect of the manufacturing process at DSP Precision Products Pvt. Ltd. The following measures are implemented to ensure that each silicon nitride ball meets high standards:

• Dimensional Inspection: Advanced measurement tools are used to verify the diameter, roundness, and surface finish of each ball. This ensures that the balls adhere to specified tolerances and dimensions.
• Hardness Testing: Hardness testing is conducted to confirm that the balls meet the required hardness levels for silicon nitride.
• Fracture Toughness Testing: Tests are performed to assess the fracture toughness of the balls, ensuring they can withstand high-stress applications without failure.
• Surface Quality Check: The surface of the balls is inspected for smoothness and the absence of defects such as cracks, pits, or blemishes.
